Four ways of solving quadratic equations- worked examples

Method 3- Solving By Using The Quadratic Formula Step 1- get the values of a, b and c to use in the formula Solve x2 + 2x - 8 = 0 Solutions x = -4 or 2 ax2 + bx + c = 0 x2 + 2x - 8 = 0 Therefore a = 1, b = 2, c = -8 Step 2- substitute these values for a, b and c into the quadratic formula and go on to simplify and solve for x x = -b ± √(b2 ...

Aptitude and Reading examination Prep sheet

Quadratic Formula Often, the simplest way to solve "ax2 + bx + c = 0" for the value of x is to factor the quadratic, set each factor equal to zero, and then solve each factor. But sometimes the quadratic is too messy, or it doesn't factor at all, or you just don't feel like factoring. While factoring may not always be successful, the
