Question

Factorise the following 12 a square b + 15 a b square

Answer 1

12a^2 b + 15 a b^2

=> 3ab(4a + 5b)

Answer 2

Answer:

The factor form of the expression is  $12a^2b+15ab^2=3ab(4a+5b)$

Step-by-step explanation:

Given : Expression $12a^2b+15ab^2$

To find : Factories the expression ?

Solution :

To factories we take the common term out.

First we factor each term,

$12a^2b=2\times 2\times 3\times a\times a\times b$

$15ab^2=3\times5\times a\times b\times b$

Take the common term, i.e. 3,a and b

So, $12a^2b+15ab^2=3ab(4a+5b)$

Thus, The factor form of the expression is  $12a^2b+15ab^2=3ab(4a+5b)$
