If , then find x²+1/x²-2 |
|
Answer» ong>Answer:
{x}^{2} + \dfrac{1}{ {x}^{2} } = \boxed{14}x 2 + x 2
1
= 14
\red\bigstar★ Given: x = 2 + √3 \green\bigstar★ To find: The value of x² + 1/x² \blue\bigstar★ Solution: x = 2 + √3 So, \FRAC{1}{x} = \frac{1}{2 + \sqrt{3} } x 1
= 2+ 3
1
Now, by rationalising the denominator, we get, \frac{1}{x} = \frac{2 - \sqrt{3} }{(2 + \sqrt{3} )(2 - \sqrt{3}) } x 1
= (2+ 3
)(2− 3
) 2− 3
\implies \frac{1}{x} = \frac{2 - \sqrt{3} }{ {(2)}^{2} - { (\sqrt{3} }^{2} )}⟹ x1 = (2) 2 −( 32 )2− 3
{ By USING (a + b)(a - b) = a² - b² } \implies \: \frac{1}{x} = \frac{2 - \sqrt{3} }{4 - 3}⟹ x1 = 4−32− 3
\implies \: \frac{1}{x} = \frac{2 - \sqrt{3} }{1}⟹ x1 = 12− 3
\implies \: \frac{1}{x} = 2 - \sqrt{3}⟹ x1 =2− 3
\therefore∴ 1/x = 2 - √3 Now, x² + 1/x² = ( x + 1/x )² - 2 So, x² + 1/x² = ( 2 + √3 + 2 - √3 )² - 2 ( By substituting the values of x and 1/x ) \implies \: {x}^{2} + \frac{1}{ {x}^{2} } = {(4)}^{2} - 2⟹x 2 + x 21 =(4) 2 −2 ( √3 and -√3 get cancelled) \implies \: {x}^{2} + \frac{1}{ {x}^{2} } = 16 - 2⟹x 2 + x 21 =16−2 \implies \: {x}^{2} + \frac{1}{ {x}^{2} } = 14⟹x 2 + x 21 =14 \therefore \: \boxed{{x}^{2} + \frac{1}{ {x}^{2} } = 14}∴ x 2 + x 21 =14
★ Concepts USED in the answer : a² - b² = ( a + b )( a - b ) Substituting the values. Rationalising the denominator. \red\bigstar★ Some identities: (a + b)(a - b) = a² - b² (a + b)² = a² + 2ab + b² (a - b)² = a² - 2ab + b² (a + b)³ = a³ + b³ + 3ab² + 3a²b a³ + b³ = ( a + b )(a² - ab + b²) a³ - b³ = (a - b) ( a² + b² + ab) |

If the sum of the first n terms of an A.P. is Sn= 4n-n². Find A.P. and nth term |
|
Answer» ong>Step-by-step explanation: We have been given , Sn = 4n -n^2
Just Think The Given Equation Of The Sum Of " n " TERMS Is correct for all the terms in the AP , So If you PUT n=1 You get Sum of 1 terms which is actually the value of FIRST term A1 . It goes like this , Sn = 4n - n^2 = 4(1) - (1)^2 = 4 - 1 = 3
so The First Term Is 3.
Sum Of 2 Terms Is ... S2 = 4(2) - (2)^2 = 4
Sum of first 2 Terms means a1 + a2 , Now you know a1 and S2 , so S2 - a1 = a2 = 4-3= 1
Now the common difference , a2- a1 = d = 1-3 = -2.
Hence The Basic Method Of Doing That was this .
Solving for a10 , an , a3 we get , a3 = -1 ; a10 = -15; an = 5 - 2n ;
That's It !

The angles of a triangle are in the ratio 4:6:2. find angles |
|
Answer» ong>Answer: The measures of the angles are 30, 60 and 90 DEGREES.
Explanation: I assume the question should read "the measures of the ANGLES of the triangle are in the ratio 2:4:6.
If the angles are in the proportion 2:4:6, the measures of the angles have the same scale FACTOR x . And, the sum of the measures of the angles of a triangle is 180 .
⇒ 2 x + 4 x + 6 x = 180
12 x = 180
12 x 12 = 180 12
x = 15
The measures of the angles are:
2 x = 2 ( 15 ) = 30
4 x = 4 ( 15 ) = 60
6 x = 6 ( 15 ) = 90 Explanation: Hope it helps you... |

|
Answer» ANSWER : 25 : 9 Solution :Let, Age of FATHER be 'x'. Age of SON be 'y'. Given, SUM of age of father and son = 100 x + y = 100 x = 100 - y Five years ago, Ratio of their ages = 2 : 1 (x-5) : (y-5) = 2 : 1 (x-5)/(y-5) = 2/1 Substitute x = 100 - y (100 - y)-5/y - 5 = 2 100 - y = 2y - 10 + 5 100 + 5 = 3y y = 35 x = 100 - y x = 100 - 35 x = 65 Ratio of their ages after 10 yrs = (65 + 10) : (35 + 10) = 75 : 45 = 25 : 9 |
