1. ALGEBRA 1 SECTION 10.4 Use Square Roots to Solve Quadratic Equations Big Idea: Solve quadratic equations Essential Question: How do you solve a quadratic equation by finding square roots?

2. Solving Quadratic Equations by Taking Square Roots  Solving x 2 = d by Taking Square Roots  If d > 0, then x 2 = d has two solutions:  If d = 0, then x 2 = d has one solution:  If d < 0, then x 2 = d has no solution.
