Only your answer will be graded; you do not need to justify your work on this page. No calculators or other technology are allowed.
1. Calculate and simplify completely:
11 1 − = 10 11
2. Expand and simplify completely: (4x − 3)(4x2 − x + 2) = 3. Simplify completely: (x3 )5 (x6 )1/3 = √ x3 + 5 x √ = 4. Simplify completely: x 5. Factor completely: x2 − 12x − 35 = 6. Find all solutions to 7x + 5 = 10; x = 7. Find all solutions to x4 − 4x2 = 0; x = 8. Find all solutions to x2 − 30 = 7x; x =
