4x^2+2.66x-1.156=0
a = 4; b = 2.66; c = -1.156;
Δ = b2-4ac
Δ = 2.662-4·4·(-1.156)
Δ = 25.5716
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{-(2.66)-\sqrt{25.5716}}{2*4}=\frac{-2.66-\sqrt{25.5716}}{8} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(2.66)+\sqrt{25.5716}}{2*4}=\frac{-2.66+\sqrt{25.5716}}{8} $
