Question

factories 3x Square -5xy-12y Square

Answer 1

$\bold{Answer :}$

Now,

3x² - 5xy - 12y²

= 3x² - (9 - 4)xy - 12y²

= 3x² - 9xy + 4xy - 12y²

= 3x (x - 3y) + 4y (x - 3y)

= (x - 3y) (3x + 4y),

which is the required factorization.

Answer 2

hey!!!

given :- 3x² - 5xy - 12y²

= 3x² - ( 9xy - 4xy ) - 12y²
= 3x² - 9xy + 4xy - 12y²
= 3x ( x - 3y ) + 4y ( x - 3y )
= ( x - 3y ) ( 3x + 4y )

cheers!!!
