__Questions:__**Factor each quadratic expression into a product of linear factors.**

- 2x
^{2}+ 15x + 7 - 7z
^{2}- 30z + 27 - 8x
^{2}- 10x - 3 - 30d
^{2}+ 7d - 15 - 10g
^{2}+ 23g + 12

Answer:

- (2x + 1)(x + 7) = 0
- (z - 3)(7z - 9) = 0
- (4x + 1)(2x - 3) = 0
- (6d + 5)(5d - 3) = 0
- (2g + 3)(5g + 4) = 0
