Solving Quadratic Equations Equations such as x 2 = 64, x 2 -5x = 0, and x 2 + 4x = 5 are called quadratic equations. This is because in each of these equations the greatest exponent of any variable is 2. Standard Form of Quadratic Equations : ax 2 + bx + c = 0 Before you select the method that you will use to solve a quadratic, you must use inverse operations to get the equation to equal zero (if necessary). When solving quadratic equations, we can use two methods: 1) Factoring 2)Quadratic FormulaSolving Quadratic Equations Using Factoring:To Solve a Quadratic Using Factoring:1)Put the quadratic equation into standard form (above).2)Factor the quadratic expression.3)Set each factor equal to zero.4)Solve each equation.5)Check each root in the original equation.For example:x2+ 4x = 5-5 -5x2+ 4x – 5 = 0(x + 5)(x – 1) = 0x + 5 = 0 x – 1 = 0-5 -5 +1 x = -5 or x = 1Now, check in the original!!!Solve each quadratic equation using factoring: +1
