Question

Solve for y=x squared -18 solve for x

Answer 1

Explanation:

`y = {x}^(2) - 18 \\ y + 18 = {x}^(2) \\ square \: root \: both \: sides \: \\ √(y + 18) = \sqrt{ {x}^(2) }`

`x = √(y + 18)`

Answer 2

√y + 18 = x

Explanation:

Let us solve it now.

y = x² - 18

Take -18 to the left side

y + 18 = x²

Now remove the square of x

√y + 18 = x
