Key Introduction What is a Quadratic Equation?
... Algebra - Rearranging and Solving Quadratic Equations The quadratic formula states that for a quadratic equation of the form y equals ax squared plus bx plus c, the value of x is equal to negative b plus or minus the square root of b squared subtract 4ac, all divided by 2a. For example, for the quad ...

... Rewrite the ORIGINAL equation using open parentheses for x. Replace the open parentheses with the solution and simplify the RHS using the order of operations. Same signs- product is positive. Since the LHS = RHS, -8 is the solution! Notice there is a negative on the LHS. That means –5 is dividing x. ...
