0=4x^2-24x+40
We move all terms to the left:
0-(4x^2-24x+40)=0
We add all the numbers together, and all the variables
-(4x^2-24x+40)=0
We get rid of parentheses
-4x^2+24x-40=0
a = -4; b = 24; c = -40;
Δ = b2-4ac
Δ = 242-4·(-4)·(-40)
Δ = -64
Delta is less than zero, so there is no solution for the equation
