9x^2+7.5x+1=0
a = 9; b = 7.5; c = +1;
Δ = b2-4ac
Δ = 7.52-4·9·1
Δ = 20.25
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{20.25}}{2*9}=\frac{-7.5-\sqrt{20.25}}{18} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(7.5)+\sqrt{20.25}}{2*9}=\frac{-7.5+\sqrt{20.25}}{18} $
