Square Root Property Practice

Square Root Property Practice

Solve each quadratic equation using the square root property. Show all your work. Remember to include both positive and negative roots where applicable.

1. Solve for x: x² = 81

2. Solve for y: y² - 49 = 0

3. Solve for z: 3z² = 75

4. To solve (x - 3)² = 25, the first step is to take the   of both sides.

5. The square root property can be used to solve quadratic equations in the form x² = k or  .

6. Solve for a: (a + 5)² = 100

7. Solve for b: 2(b - 1)² = 72

8. Which of the following equations can be solved directly using the square root property?

9. Solve for x: (x - 2)² - 18 = 0. Express your answers in simplest radical form.
