Question

$solve \: \: \: \: 4 {y}^{2} + \frac{6}{ {y}^{2} } = 11$
(hint : Substitute x for y^2)​

Answer 1

Answer: here it given hint as x = y²

4y² + 6/y² = 11

4x + 6/x = 11

4x² + 6/x = 11

4x² + 6 = 11x

4x²-11x+6 = 0

4x²-8x-3x+6 = 0

4x(x-2) -2(x-2) = 0

(4x-2) (x-2) = 0

x = 2/4 = 1/2 , x = 2

so either y² = x

x = (1/2)² = 1/4 = 0.25

or x = (2)² = 4
