Justification Subtracted 4 from both sides Divided both sides by 2 X4 Found square roots of 16 Example: Solve: 2x² = 36 2² - 36 Given ²²-18 X-2√18 Divided both sides by 2 Found square roots of 18 Simplified *- ± √(3)(3)(2) x = ±3√2 Simplified Practice: Solve and check both solutions to each quadratic equation. 1. 2² + 3 = 5 5.8 - 12/2 32 4³-16 2. -5x² + 10 = -20 4. 3x² + 3 = 39 6.-7x² + 5 = -9 АРН
