Wwhat do we do after factoring?
Factor and solve the quadratic equation x² - 10x + 21 = 0.
Look for two numbers that multiply to 21 and add up to -10.
Demonstrate the factorization method with the equation 2x² + 8x + 6 = 0 by first rewriting it in standard form.
Start solving the equation step by step.
