Example 1 Solve −10x = x 2 + 25. 2 Solve 9w = −6w 2 Applications Outline Quadratic Equations Solving Quadratic Equations The Square Root Property Theorem (The Square Root Property) If X is an algebraic expression and k is a constant, then √ √ X 2 = k if and only if X = k or X = − k . Apply the square root property as follows: Write the equation in the form X 2 = k , where X is an algebraic expression and k is a constant. Apply the squ...
