52x+20x*x=-112
We move all terms to the left:
52x+20x*x-(-112)=0
We add all the numbers together, and all the variables
52x+20x*x+112=0
Wy multiply elements
20x^2+52x+112=0
a = 20; b = 52; c = +112;
Δ = b2-4ac
Δ = 522-4·20·112
Δ = -6256
Delta is less than zero, so there is no solution for the equation
