Find the zeros of the polynomial 2 x square - 3 x minus 2 |
|
Answer» p(x)= 2x²-3x-2 To Find : The zeroes of the above polynomial. Solution : 2x²-3x-2 = 0 2x²-4x+x-2 = 0 2x(x-2)+1(x-2) = 0 (x-2)(2x+1) = 0 Here, x = 2 and x = -½. What is a polynomial? A polynomial is an algebraic expression having the degree of it's variables as a whole NUMBER. For example - 2, x , x+4, 4x³ etc. The classification of POLYNOMIALS can be DONE in two ways : • On the basis of degree : ★ Linear Polynomial - The polynomial having the degree = 1 ★ Quadratic Polynomial - The polynomial having the degree = 2 ★ Cubic Polynomial - The polynomial having the degree = 3 • On the basis of terms : ★Monomial : The polynomial having a single term only. ★ Binomial : The polynomial having two terms. ★ Trinomial : The polynomial having 3 terms. |
