4. Factoring Using the Quadratic Formula Description: Apply the quadratic formula to find the roots of the quadratic equation and express the trinomial as a product of binomials. Quadratic Formula: x =[(−b± √(b2−4ac))] / 2a
We can also use the quadratic formula:We get two answers x+ and x− (one is for the "+" case, and the other is for the "−" case in the "±") that gets us this factoring:a(x − x+)(x − x−)Example: what are the roots of 6x2 + 5x − 6 ? Substitute a=6...

Factoring Quadratic Equations using theQuadratic Formula. In some cases, recognizing some common patterns in the quadratic equation will help you to factorize the quadratic. For example, the quadratic equation could be a Perfect Square Trinomial (Square of a Sum or Square of a Difference) or Diffe...
Solve each equation to get a solution to the binomial. For x^2 – 9 = 0, for example, x – 3 = 0 and x + 3 = 0. Solve each equation to get x = 3, -3. If one of the equations is a trinomial, such as x^2 + 2x + 4 = 0, solve it using the quadratic formula, which...

How to Factor Quadratic Equations Solving with the Quadratic Formula The quadratic formula is a very efficient way to solve quadratic equations. The quadratic formula is consistent: any quadratic equation may be solved using this formula. The Quadratic Formula In order to use the quadratic formula,...
polynomials that also have rational coefficients. In such cases, the polynomial is said to "factor over the rationals." Factoring is a useful way to find rational roots (which correspond to linear factors) and simple roots involving square roots of integers (which correspond to quadratic factors...
