How do you factor x2+ 3x - 54? Factorizing Quadratics Consider the quadratic expressionf(x)=ax2+bx+c, wherea,b,care constants. Letx1andx2be solutions off(x)=0given by the well-known formula −b±b2−4ac2a. Then, we have the factorization ...
This method works for solving all quadratic equations whether they are factorable or not.Answer and Explanation: When we have a quadratic equation, ax2 + bx + c = 0, that cannot be factored, we can use the quadratic formula to solve that equation, where the...Become a member and...

Factor the quadratic equation as you would any other trinomial expression. You need to create two simple factors that, when multiplied, equal the original expression. Keep in mind the order of operations for the factors to equal the trinomial is represented by the acronym, FOIL (First, Outside...
Drop the "equals zero" part to get the factor, x − a. Apply steps (1) through (3) with the quadratic's other solution, x = b. Multiply the two factors to get a quadratic expression: (x − a)(x − b) = x2 − (a + b)x + ab. If you are given a point on ...
