Question 76888
Since I cannot format the solver here, check out the synthetic division solver <a href="http://www.algebra.com/algebra/homework/Rational-functions/synthetic-division.solver"> here</a>. If you enter the equation as 1,0,-12,16 (exactly as I have it all in the first box) and enter a test zero of -4 in the second box, you'll get a step-by-step guide to the answer.
