Answer 2

The factories form is  $3x^2-5xy-12y^2=(x-3y)(3x+4y)$

Step-by-step explanation:

Given : Expression $3x^2-5xy-12y^2$.

To find : Factories the expression ?

Solution :

Expression $3x^2-5xy-12y^2$.

We factories it by middle term split,

$3x^2-5xy-12y^2=3x^2-9xy+4xy-12y^2$

$3x^2-5xy-12y^2=3x(x-3y)+4y(x-3y)$

Take common term out,

$3x^2-5xy-12y^2=(x-3y)(3x+4y)$

Therefore, the factories form is $3x^2-5xy-12y^2=(x-3y)(3x+4y)$.
