x^2=2.5-6
We move all terms to the left:
x^2-(2.5-6)=0
We add all the numbers together, and all the variables
x^2-(-3.5)=0
We add all the numbers together, and all the variables
x^2+3.5=0
a = 1; b = 0; c = +3.5;
Δ = b2-4ac
Δ = 02-4·1·3.5
Δ = -14
Delta is less than zero, so there is no solution for the equation
