-2x(4x-2)-2x=54
We move all terms to the left:
-2x(4x-2)-2x-(54)=0
We add all the numbers together, and all the variables
-2x-2x(4x-2)-54=0
We multiply parentheses
-8x^2-2x+4x-54=0
We add all the numbers together, and all the variables
-8x^2+2x-54=0
a = -8; b = 2; c = -54;
Δ = b2-4ac
Δ = 22-4·(-8)·(-54)
Δ = -1724
Delta is less than zero, so there is no solution for the equation
