Document Summary

7:30 8:20pm, tuesday february 12, 2002: (8 points) simplify, using only positive exponents (you can assume that x, y, z 6= 0): (xy. 2 as a rational power of x (you can assume x is positive here). (b) simplify p9y. 6 by extracting squares (y could be negative here): (6 points) expand (x 2)(x. 2 + 2x + 4) to give a polynomial in standard form: (8 points) simplify. 2 4x + 3 x: (10 points) factor the following as far as possible: (a) 2x. 2 7x + 3 = (b) 4x. 2(x 5) 9(x 5) : (8 points) solve the linear equation 3(x + 3) 5 = 2( 3 x) for x. Give the exact value of x (a calculator-produced decimal will not earn full credit): (8 points) solve. 2 x(x 1) for x: (8 points) use your calculator to graph y = x.
