x^2=45-56
We move all terms to the left:
x^2-(45-56)=0
We add all the numbers together, and all the variables
x^2-(-11)=0
We add all the numbers together, and all the variables
x^2+11=0
a = 1; b = 0; c = +11;
Δ = b2-4ac
Δ = 02-4·1·11
Δ = -44
Delta is less than zero, so there is no solution for the equation
