Marisol grouped the terms and factored the GCF out of the groups of the polynomial 6x3 - 22x2 - 9x + 33. Her work is shown.

Step 1: (6x3 - 22x2) - (9x + 33)

Step 2: 2x2 (3x - 11) - 3 (3x + 11)

Marisol noticed that she does not have a common factor. Which accurately describes what Marisol should do next?

Reynaldo Chang · Answer 1

Recheck her work in step 1.

She incorrectly grouped the 2nd two terms as - (9x+33) does not equal - 9x+33

Step-by-step explanation:

She needs to recheck what she did in step 1:

- (9x+33) is not - 9x+33 but - 9x-33

In step 1 she should have wrote (6x^3-22x^2) - (9x-33)

Willow Yates · Answer 2

She should be grouping the right terms.

3x (2x^2-3) - 11 (2x^2-3)

2x^2-3 (3x-11)
