x(120+-2x)=1512
We move all terms to the left:
x(120+-2x)-(1512)=0
We add all the numbers together, and all the variables
x(-2x)-1512=0
We multiply parentheses
-2x^2-1512=0
a = -2; b = 0; c = -1512;
Δ = b2-4ac
Δ = 02-4·(-2)·(-1512)
Δ = -12096
Delta is less than zero, so there is no solution for the equation
