8x(7x+3)=2x-50
We move all terms to the left:
8x(7x+3)-(2x-50)=0
We multiply parentheses
56x^2+24x-(2x-50)=0
We get rid of parentheses
56x^2+24x-2x+50=0
We add all the numbers together, and all the variables
56x^2+22x+50=0
a = 56; b = 22; c = +50;
Δ = b2-4ac
Δ = 222-4·56·50
Δ = -10716
Delta is less than zero, so there is no solution for the equation
