Question

factorized form of 4 y square + 9 - 12 y

Answer 1

Method 1:-

$= > 4 {y}^{2} + 9 - 12y$

$= > 4 {y}^{2} - 12y + 9$

Factorize it by the middle term technique/Splitting middle term technique.

$= > 4 {y}^{2} - 6y - 6y + 9$

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

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

$= > (2y - 3) {}^{2}$

Method 2:-

=4y²+9-12y

=(2y)²+3²-2×2y×3

=(2y-3)²

I used (a-b)²=a²+b²-2ab

Answer 2

Answer:

(2y-3)whole square

Step-by-step explanation:

1.) 4y square+9-12y.

2.) (2y)square+ (3)square-2*2y*3

By the property [a square-2ab+b square]
