Multiply the following:
1. 3x ( 2x ­ 5) 2. 4x ( x2 + 7x ­ 6) 3. (x + 4)(x ­ 8) 4. ( 2x ­ 3)(4x + 5) 5. ( x ­6)2 6. ( x ­ 6)( x2 + 4x + 7)
Factor the following: (Remember to look for common factors first!)
7. 3x2 + 9x 8. 4x2 ­ 12x 9. 25x3 ­ 100x2
Factor the following:
2
10. x ­ 4x ­ 12 11. x2 ­ 9x ­ 22 12. x2 + 18x ­ 40
13. x2 + 10x + 16 14. x2 ­ 15x + 50 15. x2 ­ 36
Take out common factors first!
