Answer:
x = 4√2 or x = −4√2
Explanation:
Step 1: Add 33 to both sides.
x2 − 33 + 33 = −1 + 33
x2 = 32
Step 2: Take square root.
x = ±√32
x = 4√2
x² - 33 = -1 [ change sides ]
x² = -1 + 33
x² = 32
x = √3 [changing sides, changes power of square, (²) turns square root,√ ]
x = √4 * 4 * 2
x = 4√2 .......final answer.
