Solve for y
y=\frac{\left(x-20\right)\left(x-10\right)}{5}
Solve for x (complex solution)
x=-\sqrt{5\left(y+5\right)}+15
x=\sqrt{5\left(y+5\right)}+15
Solve for x
x=-\sqrt{5\left(y+5\right)}+15
x=\sqrt{5\left(y+5\right)}+15\text{, }y\geq -5

5y=x^{2}-30x+200
Use the distributive property to multiply x-10 by x-20 and combine like terms.
\frac{5y}{5}=\frac{\left(x-20\right)\left(x-10\right)}{5}
Divide both sides by 5.
y=\frac{\left(x-20\right)\left(x-10\right)}{5}
Dividing by 5 undoes the multiplication by 5.
