15m^2-28m=0
a = 15; b = -28; c = 0;
Δ = b2-4ac
Δ = -282-4·15·0
Δ = 784
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{784}=28$$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-28)-28}{2*15}=\frac{0}{30} =0 $$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-28)+28}{2*15}=\frac{56}{30} =1+13/15 $
