(2x-6)(2x-6)=16
We move all terms to the left:
(2x-6)(2x-6)-(16)=0
We multiply parentheses ..
(+4x^2-12x-12x+36)-16=0
We get rid of parentheses
4x^2-12x-12x+36-16=0
We add all the numbers together, and all the variables
4x^2-24x+20=0
a = 4; b = -24; c = +20;
Δ = b2-4ac
Δ = -242-4·4·20
Δ = 256
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{256}=16$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-24)-16}{2*4}=\frac{8}{8} =1 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-24)+16}{2*4}=\frac{40}{8} =5 $
