The answers to the expressions are:
- (x² + 15x + 65)+(2x - 5)(3x + 8) simplifies to 7x² + 16x + 25. The first blank is (B).
- (4x + 1)(3x - 4)-(5x² - 10x - 12) simplifies to 7x² – 3x + 8. The second blank is (D).

Others are:
- (8x² + 91x + 4)+(3x +2)(x - 5) simplifies to 11x² + 6x - 6. The second blank is (A).
- (6x + 1)(3x - 7) - (7x² -34x - 20) simplifies to 11x² - 5x + 13. The second blank is (C).
Note that:
(x²+15x+65)+(2x-5)*(3x+8)
(x²+15x+65)+(6x²+16x-15x-40)
(7x²+16x+25)
Therefore its answer will be letter B which is (7x²+16x+25)
