0=17x^2-50x+225
We move all terms to the left:
0-(17x^2-50x+225)=0
We add all the numbers together, and all the variables
-(17x^2-50x+225)=0
We get rid of parentheses
-17x^2+50x-225=0
a = -17; b = 50; c = -225;
Δ = b2-4ac
Δ = 502-4·(-17)·(-225)
Δ = -12800
Delta is less than zero, so there is no solution for the equation
