If alpha and beta are the zeroes of the polynomial f(x)= x^2 + px +q form a polynomial whose zeroes are (α+β)^2 and (α - β )^2 |
|
Answer» Answer: We have polynomial f ( x ) = x2 + p x + Q And Roots are α and β And we KNOW from relationship between zeros and COEFFICIENT . Sum of zeros = −Coefficient of xCoefficient of x2 So, α + β = - p ------ ( 1 ) Taking whole square on both hand side , we get ( α + β )2 = p 2 ------ ( 2 ) ⇒α2 + β2 + 2 α β = P2⇒α2 + β2 + 2 α β − 2αβ + 2αβ= p2⇒α2 + β2 − 2 α β +4 αβ= p2⇒(α − β) 2 +4 αβ= p2 −−−− ( 3 ) And Products of zeros = Constant termCoefficient of x2 So, α β = q , Substitute that value in equation 3 , we get ⇒(α− β)2 + 4 (q ) = p2⇒(α− β)2 +4 q= p2⇒(α− β)2 = p2 − 4 q −−−− ( 4 ) Now we add equation 2 and 4 and get (α + β)2 + (α − β)2 = p2 + p2 − 4 q= 2 p2 − 4 q And we multiply equation 2 and 4 and get (α + β)2 × (α − β)2 = p2( p2 − 4 q)= p4 − 4 p2q And we know formula for polynomial when sum of zeros and product of zeros we know : Polynomial = k [ x2 - ( Sum of zeros ) x + ( Product of zeros ) ] , Here k is any NON zero real number. Substitute values , we get Quadratic polynomial = k [ x2 - ( 2 p2 - 4 q) x + ( 2 p4 - 4 p2q) ]
= x2 - ( 2 p2 - 4 q) x + ( 2 p4 - 4 p2q) [ taking k = 1 ] ( Ans ) Hope this information will clear your doubts about topic i 后排哦 i他 河流怕 有 |

Exponential function versus arithmetic function |
Answer» EXPONENTIAL FUNCTIONIn addition to linear, quadratic, rational, and radical functions, there are exponential functions. Exponential functions have the form f(x) = bx, where b > 0 and b ≠ 1. Just as in any exponential expression, b is called the base and x is called the exponent.
An example of an exponential function is the growth of bacteria. Some bacteria double every hour. If you start with 1 bacterium and it doubles every hour, you will have 2X bacteria after x hours. This can be written as f(x) = 2x.
Before you start, f(0) = 20 = 1 After 1 hour f(1) = 21 = 2 In 2 hours f(2) = 22 = 4 In 3 hours f(3) = 23 = 8 and so on.
With the definition f(x) = bx and the restrictions that b > 0 and that b ≠ 1, the domain of an exponential function is the set of all real numbers. The range is the set of all positive real numbers. The following graph shows f(x) = 2x. ARITHMETIC FUNCTIONA complex-valued function, the domain of definition of which is one of the following sets: the set of natural numbers, the set of rational integers, the set of integral ideals of a given algebraic number field, a lattice in a multi-dimensional coordinate space, etc. These are arithmetic functions in the wide sense. However, the term is often employed to denote a function of the above type with special arithmetic properties. The most commonly occurring arithmetic functions have traditional SYMBOLIC notations: ϕ(n) is the Euler function; d(n) or τ(n) is the number of divisors; μ(n) is the Möbius function; Λ(n) is the Mangoldt function; σ(n) is the sum of divisors of the number n. Arithmetic functions also include the integral part of a number, [x], and the FRACTIONAL part of a number, {x}. Arithmetic functions giving the number of solutions of an equation are also studied; for example, r(n) is the number of integer solutions x and y of the equation x2+y2=n in the Goldbach problem; J(N) is the number of solutions in prime numbers of the equation N=p1+p2+p3. Other arithmetic functions express the quantity of numbers satisfying certain conditions; thus, for instance, the function π(x) — the number of primes not larger than x — describes the distribution of primes; π(x,q,l) gives the number of primes not larger than x in the arithmetic progression p≡l(modq). The Chebyshev functions also deal with properties of primes: θ(x) is the sum of the natural logarithms of the prime numbers up to x, while ψ(x)=∑n≤xΛ(n) (cf. Chebyshev function). Algebraic number theory deals with generalizations of the above arithmetic functions of a natural argument. Thus, for instance, in an algebraic field K of degree n, Euler's function ϕ(U) — the number of residue classes by the ideal U mutually prime with U — is introduced for an integral ideal U. Arithmetic functions appear and are employed in studies on the properties of numbers. However, the theory of arithmetic functions is also of independent interest. The laws governing the variations of arithmetic functions cannot usually be described by simple formulas, and the asymptotic behaviour in terms of numerical functions is determined. Since many arithmetic functions are not monotone, the study of their average values is of great importance (cf. Average order of an arithmetic function). An important class of arithmetic functions is constituted by the multiplicative arithmetic functions and the additive arithmetic functions. The problem of the distribution of their values is studied in probabilistic number theory [5]. If this helps please mark as brainliest and i couldnt attach the graph it wont load |
