1. Subtract the following polynomials: (4x² – 9x – 7) – (3x² – 5x – 6)
2. Multiply and combine like terms:  (x – 10)(x + 9)
3. Factor completely:  10r3s2 + 25r2s2 – 15r2s3
4. Factor the trinomial:  3×2 + 7x + 2
5. Factor completely:  xy - 3x + 4y – 12
6. Solve the equation by factoring:  x2 – 2x – 3 = 0
