1. Find x if
x2 + 7x + 12 = 0
2. Find x if
x2 + 2x − 4 = 0
(Try this one two ways...one with and one without the quadratic formula)
3. Simplify (ie, write with fewer fraction bars)
1
x+h
−
h
4. Solve for x:
1
x
x2 + 8x + 3
= 2x + 8
x−3
5. Simplify (write as separate fractions)
x3 + 2x2 − 1
2x
6. Simplify
x2 − 10x + 16
x2 + x − 6
7. Rationalize the Denominator in
√
x2
1
2
−4−2
