Solve for y
y=\left(12464x-3\right)^{2}-5
Solve for x
x=\frac{-\sqrt{y+5}+3}{12464}
x=\frac{\sqrt{y+5}+3}{12464}\text{, }y\geq -5

y=155351296x^{2}-74784x+9-5
Use binomial theorem \left(a-b\right)^{2}=a^{2}-2ab+b^{2} to expand \left(12464x-3\right)^{2}.
y=155351296x^{2}-74784x+4
Subtract 5 from 9 to get 4.
