Is y^2 = 4 - x^2 the same as:
y= 2 - x
OR
y= (4 - x^2)/y
Thank you!
Hi RB89,
If you're wanting to solve for y, you will need to take the square root of both sides of the equation.
And that's about it.
Now, if you had something like: , you could get to because the right side of the equation was a perfect square. That wasn't the case in your example.
