Corrected answer: $$2\left(16x^2+6x+3\right)$$

Corrected answer: $$2x\left(16x^2+6x+3\right)$$

Corrected answer: $$3\left(15x^2+4x+2\right)$$

Error: the student forgot to bring down the GCF with the factored problem.

Error: the GCF should have been 2x not just 2.

  $$2x^2\left(7+5x^2-9x\right)$$  

$$2x\left(5x^3-9x^2+7x\right)$$  

$$2x^2\left(5x^2-9x+7\right)$$  

$$2x\left(7x+5x^3-9x^2\right)$$

The greatest common factor is not 5x. It is 15x

When factoring the polynomial, there should be three terms inside the parenthesis.

It is not in standard form

Corrected answer: $$15x\left(x^2+2x+3\right)$$

Corrected answer: $$5x\left(3x^2+2x+1\right)$$

(2x + 5) (2x - 5)

(2x - 5)²

(2x + 5)²

2x + 5(2x - 5)
