2x^2+5x-3400=0
a = 2; b = 5; c = -3400;
Δ = b2-4ac
Δ = 52-4·2·(-3400)
Δ = 27225
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{27225}=165$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(5)-165}{2*2}=\frac{-170}{4} =-42+1/2 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(5)+165}{2*2}=\frac{160}{4} =40 $
