0=5x^2-20x+34
We move all terms to the left:
0-(5x^2-20x+34)=0
We add all the numbers together, and all the variables
-(5x^2-20x+34)=0
We get rid of parentheses
-5x^2+20x-34=0
a = -5; b = 20; c = -34;
Δ = b2-4ac
Δ = 202-4·(-5)·(-34)
Δ = -280
Delta is less than zero, so there is no solution for the equation
