4.9x^2+15x-8=0
a = 4.9; b = 15; c = -8;
Δ = b2-4ac
Δ = 152-4·4.9·(-8)
Δ = 381.8
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{-(15)-\sqrt{381.8}}{2*4.9}=\frac{-15-\sqrt{381.8}}{9.8} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(15)+\sqrt{381.8}}{2*4.9}=\frac{-15+\sqrt{381.8}}{9.8} $
