11.615=x^2+5x+65
We move all terms to the left:
11.615-(x^2+5x+65)=0
We get rid of parentheses
-x^2-5x-65+11.615=0
We add all the numbers together, and all the variables
-1x^2-5x-53.385=0
a = -1; b = -5; c = -53.385;
Δ = b2-4ac
Δ = -52-4·(-1)·(-53.385)
Δ = -188.54
Delta is less than zero, so there is no solution for the equation
