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.
