0=10x^2-4x+8
We move all terms to the left:
0-(10x^2-4x+8)=0
We add all the numbers together, and all the variables
-(10x^2-4x+8)=0
We get rid of parentheses
-10x^2+4x-8=0
a = -10; b = 4; c = -8;
Δ = b2-4ac
Δ = 42-4·(-10)·(-8)
Δ = -304
Delta is less than zero, so there is no solution for the equation
