Answer 1

Answer: The answer is x = +/- $\sqrt{y+1}$.

Step-by-step explanation: You can solve this by simply rearranging the equation to make x by itself.

-$x^{2}$ = -y - 1

Then cancel out the -1 by dividing it through to obtain.

$x^{2} =y+1$

The final step is to square root both sides to get rid of the exponent.

x = $\sqrt{y+1}$

This should be the answer since square roots have a +/-.

Answer 2

If x^2 = y
x = +- y

So y = x^2 - 1
x^2 = y+1
x = +- square root (y+1)
