X^2+13X=10.3125
We move all terms to the left:
X^2+13X-(10.3125)=0
We add all the numbers together, and all the variables
X^2+13X-10.3125=0
a = 1; b = 13; c = -10.3125;
Δ = b2-4ac
Δ = 132-4·1·(-10.3125)
Δ = 210.25
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{-(13)-\sqrt{210.25}}{2*1}=\frac{-13-\sqrt{210.25}}{2} $$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(13)+\sqrt{210.25}}{2*1}=\frac{-13+\sqrt{210.25}}{2} $
