7x^2+1.5x-13.5=0
a = 7; b = 1.5; c = -13.5;
Δ = b2-4ac
Δ = 1.52-4·7·(-13.5)
Δ = 380.25
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{-(1.5)-\sqrt{380.25}}{2*7}=\frac{-1.5-\sqrt{380.25}}{14} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1.5)+\sqrt{380.25}}{2*7}=\frac{-1.5+\sqrt{380.25}}{14} $
