Solve for x:
-56 + √x = -39
Add 56 to both sides: √x = 17
Square both sides (√x ≥ 0 so no extraneous root): x = 17^2 = 289
Check: -56 + √289 = -56 + 17 = -39. Correct.
-56 + √x = -39
Add 56 to both sides: √x = 17
Square both sides (√x ≥ 0 so no extraneous root): x = 17^2 = 289
Check: -56 + √289 = -56 + 17 = -39. Correct.
