34=6.5^2+l^2
We move all terms to the left:
34-(6.5^2+l^2)=0
We get rid of parentheses
-l^2+34-6.5^2=0
We add all the numbers together, and all the variables
-1l^2-8.25=0
a = -1; b = 0; c = -8.25;
Δ = b2-4ac
Δ = 02-4·(-1)·(-8.25)
Δ = -33
Delta is less than zero, so there is no solution for the equation
