Question

Factor the polynomial below.

Answer 1

D

Explanation:

The question is to factor
`2a^2-10a+3ab-15b`

We group the first 2 terms and find common factor. We group the last 2 terms and find common factor. Simplifying we get:

`2a^2-10a+3ab-15b\\=(2a^2-10a)+(3ab-15b)\\=2a(a-5)+3b(a-5)\\=(2a+3b)(a-5)`

Clearly, answer choice D is correct.
