Binomial Square

Practice Problems

Try these practice problems. Work the problem on another piece of paper, then select the correct choice.

1.) Factor x² + 2x + 1

(x + 1)(x + 1)
(x - 1)(x - 1)
(x + 1)(x - 1)
(x + 2)(x - 1)

2.) Factor 9x² + 12x + 4

(3x - 2)(3x - 2)
(3x + 2)(3x - 2)
(3x + 2)(3x + 2)
(3x + 4)(3x - 1)

3.) Factor 4x² - 20x + 25

(2x + 5)(2x + 5)
(2x + 5)(2x - 5)
(4x - 25)(x + 1)
(2x - 5)(2x - 5)
