(2x-4)(2x+6)=36
We move all terms to the left:
(2x-4)(2x+6)-(36)=0
We multiply parentheses ..
(+4x^2+12x-8x-24)-36=0
We get rid of parentheses
4x^2+12x-8x-24-36=0
We add all the numbers together, and all the variables
4x^2+4x-60=0
a = 4; b = 4; c = -60;
Δ = b2-4ac
Δ = 42-4·4·(-60)
Δ = 976
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{976}=\sqrt{16*61}=\sqrt{16}*\sqrt{61}=4\sqrt{61}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(4)-4\sqrt{61}}{2*4}=\frac{-4-4\sqrt{61}}{8} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(4)+4\sqrt{61}}{2*4}=\frac{-4+4\sqrt{61}}{8} $
