x^2+7.5x+14=39
We move all terms to the left:
x^2+7.5x+14-(39)=0
We add all the numbers together, and all the variables
x^2+7.5x-25=0
a = 1; b = 7.5; c = -25;
Δ = b2-4ac
Δ = 7.52-4·1·(-25)
Δ = 156.25
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{-(7.5)-\sqrt{156.25}}{2*1}=\frac{-7.5-\sqrt{156.25}}{2} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(7.5)+\sqrt{156.25}}{2*1}=\frac{-7.5+\sqrt{156.25}}{2} $
