Solve for y
y=\left(3x-10\right)\left(3x-2\right)
Solve for x (complex solution)
x=-\frac{\sqrt{y+16}}{3}+2
x=\frac{\sqrt{y+16}}{3}+2
Solve for x
x=-\frac{\sqrt{y+16}}{3}+2
x=\frac{\sqrt{y+16}}{3}+2\text{, }y\geq -16

y=9\left(x^{2}-4x+4\right)-16
Use binomial theorem \left(a-b\right)^{2}=a^{2}-2ab+b^{2} to expand \left(x-2\right)^{2}.
y=9x^{2}-36x+36-16
Use the distributive property to multiply 9 by x^{2}-4x+4.
y=9x^{2}-36x+20
Subtract 16 from 36 to get 20.
