Hello, I have been going through the Wisconsin Placement Exam sample test. I'm trying to figure out how to find the solution set for x^{6} – 7x^{3} + 12.
I have tried having u = x^{3} and solving for u^{2}-7u+12, but I'm unsure what to do once I get (u - 4)(u - 3).
Would someone help me figure out how to solve this type of problem?
