[PDF] 8 4 factoring trinomials ax2 bx c answers

  • Can all trinomials of the form x2 bx c be factored?

    If a trinomial of the form x2+bx+c factors into the product of two binomials, then the coefficient of the middle term is the sum of factors of the last term. Not all trinomials can be factored as the product of binomials with integer coefficients. In this case, we call it a prime trinomial.

  • What is the algebra ax2 bx c?

    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.
  • 1Multiply the coe?cients a and c and determine their product ac. 2Circle the pair in the list produced in step 1 whose sum equals b, the coef?cient of the middle term of ax2+bx+c.3Replace the middle term bx with a sum of like terms using the circled pair from step 2.4Factor by grouping.
