What is the result of isolating y^2 in the equation below (x-2)^2+y^2=64?

Solution:

We want to isolate y^{2} from the equation (x-2)^{2} +y^{2} =64

To isolate y^{2}, we must try to get y^{2} alone

So, We must subtract (x-2)^{2} from both sides

(x-2)^{2}-(x-2)^{2}  +y^{2} =64-(x-2)^{2}

0 +y^{2} =64-(x-2)^{2}

y^{2} =64-(x^{2}-4x+4)

Distributing '-' inside parenthesis

y^{2} =64-x^{2} +4x -4

y^{2} =60-x^{2} +4x

Answer:

y=\sqrt[2]{64-(x-2)^{2} }

Step-by-step explanation:

Remember that in order to isolate something form a function you just have to clear the equation for that term:

(x-2)^2+y^2=64\\y^2=64-(x-2)^2\\y=\sqrt[2]{64-(x-2)^2}

So the first step is clearing (x-2)^2 form that side of the equation, so since it is adding we send it to the other side withdrawing, now we are left wit y^2, after this we just have to send the exponent as a root to the other side and we finished isolating Y.
