In this video, we solve the cubic equation:
𝑥^3 + 𝑥^2 = 12
We’ll go step-by-step through:
• Moving all terms to one side
• Using the Rational Root Theorem
• Synthetic division
• Factoring the cubic
• Solving the resulting quadratic
• Finding both real and complex solutions
By the end, you’ll see how one real root leads to two complex conjugate solutions.
This is a great review problem for Algebra 2, Precalculus, SAT Math, and college algebra students.
