How do you solve X squared equals 40

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 ,

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

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
