Question

-4square root x+9=20

Answer 1

Is this the equation?

\(-4\sqrt{x + 9} = 20 \)

Answer 2

Yes

Answer 3

First, divide both sides by -4 to isolate the square root.
Then square both sides.
Then solve for x.
Once you have a value for x, be sure to check it in the original equation since squaring both sides can introduce extraneous (false) solutions.
