Question

Factor completely 3ab − 5ax + 9b − 15x.

(3b + 5x)(a + 3)
(3b − 5x)(a + 3)
(3b − 5x)(a − 3)
Prime

Answer 1

(3b - 5x)(a +3) is the answer

Answer 2

`(a+3)(3b-5x)`

Explanation:

We are given that an expression

`3ab-5ax+9b-15x`

We have to find the factors of given expression

Rearrange the terms of given expression then we get

`3ab+9b-5ax-15x`

Now, we taking common 3b from first two terms and -5 x from last two terms

`3b(a+3)-5x(a+3)`

Now. taking common a+3 then we get

`(a+3)(3b-5x)`
