(2x+3)(6x+1)=180
We move all terms to the left:
(2x+3)(6x+1)-(180)=0
We multiply parentheses ..
(+12x^2+2x+18x+3)-180=0
We get rid of parentheses
12x^2+2x+18x+3-180=0
We add all the numbers together, and all the variables
12x^2+20x-177=0
a = 12; b = 20; c = -177;
Δ = b2-4ac
Δ = 202-4·12·(-177)
Δ = 8896
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{8896}=\sqrt{64*139}=\sqrt{64}*\sqrt{139}=8\sqrt{139}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(20)-8\sqrt{139}}{2*12}=\frac{-20-8\sqrt{139}}{24} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(20)+8\sqrt{139}}{2*12}=\frac{-20+8\sqrt{139}}{24} $
