x = ±sqrt (40)
x = ±2 sqrt (10)
Step-by-step explanation:
x^2 = 40
Take the square root of each side
sqrt (x^2) = ±sqrt (40)
x = ±sqrt (40)
x = ±sqrt (4) sqrt (10)
x = ±2 sqrt (10)

Good evening,
Answer:
x = √40 or x = - √40
Step-by-step explanation:
x² = 40 ⇌ x² - 40 = 0 ⇌ x² - (√40) ² = 0 ⇌ (x - √40) (x + √40) = 0
⇌ x = √40 or x = - √40
