Question

Which of the following is a factor of the polynomial below?

Answer 1

C

Explanation:

The question is to factor
`6a-9ab+4-6b`

We look for common factors in terms and simplify:

`6a-9ab+4-6b\\=(6a-9ab)+(4-6b)\\=3a(2-3b)+2(2-3b)\\=(3a+2)(2-3b)`

The last line shows the simplified form and the 2 factors of the expression.

We can clearly see that Answer Choice C is a factor.
