Given ::- (a²+9)x²+ 13x +6a = 0
Roots are α and 1/α
Solution ::-
comparing the given equation with ax² + bx + c = 0
a = (a²+9) , b = 13 c = 6a
α + 1/α = -b/a
α² + 1 / α = - 13 / (a² + 9)
α × 1/α = c/a
1 = 6a / (a² + 9)
(a² + 9) = 6a
a² - 6a + 9 = 0
By factorisation method,
a² -3a -3a + 9 = 0
a ( a - 3 ) -3 (a - 9) = 0
(a - 3) (a - 9) = 0
So, a = 3 or a = 9
Therefore, the value of a is 3 or 9.
