0=10x^2-7x+5
We move all terms to the left:
0-(10x^2-7x+5)=0
We add all the numbers together, and all the variables
-(10x^2-7x+5)=0
We get rid of parentheses
-10x^2+7x-5=0
a = -10; b = 7; c = -5;
Δ = b2-4ac
Δ = 72-4·(-10)·(-5)
Δ = -151
Delta is less than zero, so there is no solution for the equation
