(12x+28)(3x+62)=180
We move all terms to the left:
(12x+28)(3x+62)-(180)=0
We multiply parentheses ..
(+36x^2+744x+84x+1736)-180=0
We get rid of parentheses
36x^2+744x+84x+1736-180=0
We add all the numbers together, and all the variables
36x^2+828x+1556=0
a = 36; b = 828; c = +1556;
Δ = b2-4ac
Δ = 8282-4·36·1556
Δ = 461520
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{461520}=\sqrt{144*3205}=\sqrt{144}*\sqrt{3205}=12\sqrt{3205}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(828)-12\sqrt{3205}}{2*36}=\frac{-828-12\sqrt{3205}}{72} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(828)+12\sqrt{3205}}{2*36}=\frac{-828+12\sqrt{3205}}{72} $
