9x^2+28x-37=0
a = 9; b = 28; c = -37;
Δ = b2-4ac
Δ = 282-4·9·(-37)
Δ = 2116
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{2116}=46$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(28)-46}{2*9}=\frac{-74}{18} =-4+1/9 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(28)+46}{2*9}=\frac{18}{18} =1 $
