34s^2-70s=0
a = 34; b = -70; c = 0;
Δ = b2-4ac
Δ = -702-4·34·0
Δ = 4900
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$s_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$s_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{4900}=70$$s_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-70)-70}{2*34}=\frac{0}{68} =0 $$s_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-70)+70}{2*34}=\frac{140}{68} =2+1/17 $
