50x^2=56x^2+20-6
We move all terms to the left:
50x^2-(56x^2+20-6)=0
We get rid of parentheses
50x^2-56x^2-20+6=0
We add all the numbers together, and all the variables
-6x^2-14=0
a = -6; b = 0; c = -14;
Δ = b2-4ac
Δ = 02-4·(-6)·(-14)
Δ = -336
Delta is less than zero, so there is no solution for the equation
