X2-31X+10=0
We add all the numbers together, and all the variables
X^2-31X+10=0
a = 1; b = -31; c = +10;
Δ = b2-4ac
Δ = -312-4·1·10
Δ = 921
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-31)-\sqrt{921}}{2*1}=\frac{31-\sqrt{921}}{2} $$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-31)+\sqrt{921}}{2*1}=\frac{31+\sqrt{921}}{2} $
