5x^2+3x-42=0
a = 5; b = 3; c = -42;
Δ = b2-4ac
Δ = 32-4·5·(-42)
Δ = 849
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{-(3)-\sqrt{849}}{2*5}=\frac{-3-\sqrt{849}}{10} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(3)+\sqrt{849}}{2*5}=\frac{-3+\sqrt{849}}{10} $
