Big Idea: Solve quadratic equations Essential Question: How do you solve a quadratic equation by finding square roots? Algebra 1section 10.4 Use Square Roots to Solve Quadratic Equations
Solving Quadratic Equations by Taking Square Roots • Solving x2 = d by Taking Square Roots • If d > 0, then x2 = d has two solutions: • If d = 0, then x2 = d has one solution: • If d < 0, then x2 = d has no solution.
Examples • Solve the following quadratic equations. a) c) b) d)
