Question

Use the square root property to solve: 5x^2+8 =133 Please help

Answer 1

Answer:

• x = ± 5

Step-by-step explanation:

See the steps

• 5x^2+8 = 133
• 5x^2 = 133 - 8
• 5x^2 = 125
• x^2 = 125/5
• x^2 = 25
• √x² = √25
• x = ± 5

Answer 2

Answer:

x=5

x=−5

Step-by-step explanation:

5x^2+8 =133

Subtract 8 from both sides.

5x^2=133−8

Subtract 8 from 133 to get 125.

5x^2=125

Divide both sides by 5.

x^2=125/5

Divide 125 by 5 to get 25.

x^2=25

Take the square root of both sides of the equation.

x=5

x=−5
