[PDF] 7 6 additional practice factoring ax2 bx c

  • What is the first step to Factorise ax2 BX C?

    First, factor out all constants which evenly divide all three terms. If a is negative, factor out -1. This will leave an expression of the form d (ax2 + bx + c), where a, b, c, and d are integers, and a > 0. We can now turn to factoring the inside expression.
  • The form ax2 + bx + c = 0 is called standard form of a quadratic equation. Before solving a quadratic equation using the Quadratic Formula, it's vital that you be sure the equation is in this form. If you don't, you might use the wrong values for a, b, or c, and then the formula will give incorrect solutions.
