Factor x² – 9.

(x – 3)(x + 3)

(x – 3)(x – 3)

(x – 9)(x – 9)

cannot be factored

How should the 19x in 6x² + 19x + 10 be split up in order to factor the polynomial?

3x + 16x

4x + 15x

5x + 14x

6x + 13x

Which of these can be factored?

x² + 5x + 36

x² + 5x – 36

x² – 5x + 36

x² + 36x + 5

10x² + 37x + 7 is factored below. Which step is incorrect?

Step one: 10x² + 35x + 2x + 7

Step two: 5x(2x + 7) + 1(2x + 7)

Step three: (5x + 1)(2x + 7)

All three steps are correct.
