Question

9y⁴-13y²+4, Factorize the given equation.

Answer 1

Answer :

Now, 9y⁴ - 13y² + 4

= 9y⁴ - (9 + 4)y² + 4

= 9y⁴ - 9y² - 4y² + 4

= 9y² (y² - 1) - 4 (y² - 1)

= (y² - 1) (9y² - 4)

= (y + 1) (y - 1) (3y + 2) (3y - 2),

Answer 2

Heya !!

Here is your answer...

${9y}^{4} - {13y}^{2} + 4$

$= > {9y}^{4} - (9 + 4) {y}^{2} + 4$

$= > {9y}^{4} - {9y}^{2} - {4y}^{2} + 4$

$= > {9y}^{2} ( {y}^{2} - 1) - 4( {y}^{2} - 1)$

$= > ({9y}^{2} - 4)( {y}^{2} - 1)$

$= > (3y - 2)(3y + 2)(y - 1)(y + 1)$

Hope it helps...
