-41u^2-12=-5u^2
We move all terms to the left:
-41u^2-12-(-5u^2)=0
We get rid of parentheses
-41u^2+5u^2-12=0
We add all the numbers together, and all the variables
-36u^2-12=0
a = -36; b = 0; c = -12;
Δ = b2-4ac
Δ = 02-4·(-36)·(-12)
Δ = -1728
Delta is less than zero, so there is no solution for the equation
