Factor k 2 + 8k + 15. (k + 1) (k + 15) (k + 8) (k + 7) (k + 3) (k + 5)

Find the quotient. (6x 2 + 23x + 20) : (5 + 2x) 3x - 4 3x + 4 3x + 19

Select the correct difference. 5d 2 + 4d - 3 less 3d 2 - 2d + 4 2d2 + 2d + 1 2d2 + 6d - 7 2d2 + 6d + 7 - 2d2 - 6d + 1

Factor 4b 2 - 9. (4b + 3) (b - 3) (2b + 3) (2b - 3) (2b - 4) (2b - 5)

K² + 8k + 15

k² + 5k + 3k + 15

k (k) + k (5) + 3 (k) + 3 (5)

k (k + 5) + 3 (k + 5)

(k + 3) (k + 5)

The answer is D.

3x + 4

2x + 5|6x² + 23x + 20

6x² + 15x

8x + 20

8x + 20

0

The answer is C.

(5d² + 4d - 3) - (3d² - 2d + 4)

(5d² - 3d²) + (4d + 2d) + (-3 - 4)

2d² + 6d - 7

The answer is B.

4b² - 9

4b² + 6b - 6b - 9

2b (2b) + 2b (3) - 3 (2b) - 3 (3)

2b (2b + 3) - 3 (2b + 3)

(2b - 3) (2b + 3)

The answer is C.
