7b^2-41b+30=0
a = 7; b = -41; c = +30;
Δ = b2-4ac
Δ = -412-4·7·30
Δ = 841
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$b_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$b_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{841}=29$$b_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-41)-29}{2*7}=\frac{12}{14} =6/7 $$b_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-41)+29}{2*7}=\frac{70}{14} =5 $
