Question

which of the following are factors of 6x^2 + 30x - 36? Select all that apply

1. x-1
2. x+2
3. 2
4. 3
5. x+6
6. x-6
7. x-2

Answer 1

Answer:\\

the correct answers are

x-1

2

3

x+6

Answer 2

Answer with Step-by-step explanation:

we have to calculate the factors of the polynomial:

  $6x^2 + 30x - 36$

This could also be written as:

$6(x^2+5x-6)\\\\=6(x^2+6x-x-6)\\\\=6(x(x+6)-1(x+6))\\\\=2\times 3\times (x-1)(x+6)$

Hence, the factors of the polynomial   $6x^2 + 30x - 36$ are:

x-1,x+6,2,3

Hence, the correct options are:

1. x-1

3. 2

4. 3

5. x+6
