Please show work if you can

Answer 1

-5, 5

Explanation:

Original equation

`5x^(2) +8 = 133`

Move 8 to the right

`5x^(2) = 133 - 8`

Solve

`5x^(2) = 125`

Divide both sides by 5

`x^(2) = 25`

Take the square root of both sides

`x =` ±
`5`

Separate into two different equations

`\left \{ {{x=-5} \atop {x=5}} \right.`
