Question

1.factorisation of 12a²b+15ab²is

(a). 3a(4ab+5b²)



​

Answer 1

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)
