Answer:

2 {x}^{2}  + 13x + 15 \\ 2 {x}^{2}  + 10x + 3x + 15 \\ 2x(x + 5) + 3(x + 5) \\ (2x + 3)(x + 5)

5 {x}^{2} +  21x + 4 \\ 5 {x}^{2}  + 20x + x + 4 \\ 5x(x + 4) + 1(x + 4) \\ (5x + 1)(x + 4) \\

7 {x}^{2}  - 59x + 24 \\  7 {x}^{2}  - 56x - 3x + 24 \\ 7x(x - 8) - 3(x - 8) \\ (7x - 3)(x - 8)

2 {x}^{2}  + 11x - 13 \\ 2 {x}^{2}   - 2x + 13x - 13 \\ 2x(x - 1) + 13(x - 1) \\ (2x + 13)(x - 1)

8 {x}^{2}  + 29x - 12 \\ 8 {x}^{2}  + 32x - 3x - 12 \\ 8x(x + 4) - 3(x + 4) \\ (8x - 3)(x + 4) \\  \\

12 {x}^{2}  - 7x - 12 \\ 12 {x}^{2}   + 9x - 16x- 12 \\3x(4x + 3) - 4(4x + 3) \\ (3x - 4)(4x + 3)

- 12 {x}^{2}  - 35x - 18 \\  - 12 {x}^{2}  - 8x - 27x- 18 \\  - 4x(3x - 2) - 9(3x - 2) \\ ( - 4x - 9)(3x - 2)
