Question

please give me right answer​

Answer 1

Answer:

option (a) is the correct answer

Answer 2

Answer:

opinion a) 3ab(4a + 5b)

The factor form of the expression is 12a²b+15ab² = 3ab(4a+5b)

Given : Expression 12a²b+15ab²

Solution :

To factories we take the common term out.

First we factor each term,

12a²b=2\times 2\times 3\times a\times a\times b

15ab²=3\times5\times a\times b\times b

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

So, 12a²b+15ab² = 3ab(4a+5b)

Thus, The factor form of the expression is 12a²b+15ab² = 3ab(4a+5b).
