Simple ways to solve quadratic equations
WebbYou can solve quadratic equations by graphing, factoring, completing the square, & the quadratic formula. Graphing gives a good visual, but it is hard to find values of x from a graph with no equation. If factoring is hard, the quadratic formula (a shortcut for completing the square) helps. WebbExample of the quadratic formula to solve an equation. Use the formula to solve theQuadratic Equation: y = x 2 + 2 x + 1 . Just substitute a,b, and c into the general formula: a = 1 b = 2 c = 1. Below is a picture representing the graph of y = x² + 2x + 1 and its solution.
