(Z^2-6Z+34)-4(Z^2-6Z+34)=0
We multiply parentheses
-4Z^2+(Z^2-6Z+34)+24Z-136=0
We get rid of parentheses
-4Z^2+Z^2-6Z+24Z+34-136=0
We add all the numbers together, and all the variables
-3Z^2+18Z-102=0
a = -3; b = 18; c = -102;
Δ = b2-4ac
Δ = 182-4·(-3)·(-102)
Δ = -900
Delta is less than zero, so there is no solution for the equation
