1. What is the remainder of (x^3 + 2x^2 - 5x+4) /(x-3) I think the answer is 34??

2. Evaluate (4+5i)(2+2i)

=4(2) +4(2i) + 5i(2) + 5i(2i) = 8 + 8i + 10i+10i^2(-1)

=-2 + 18i

3. Using Rational Roots Theorem, list all possible rational root of f(x) = 2x^3 - 3x^2 + 5x+6

Possible roots are p/a = -+1, -+2, +-3, -+6. -+3/2
