(9.5e-2)(4.15e-4)=0
We multiply parentheses ..
(+36e^2-36e-8e+8)=0
We get rid of parentheses
36e^2-36e-8e+8=0
We add all the numbers together, and all the variables
36e^2-44e+8=0
a = 36; b = -44; c = +8;
Δ = b2-4ac
Δ = -442-4·36·8
Δ = 784
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$e_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$e_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{784}=28$$e_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-44)-28}{2*36}=\frac{16}{72} =2/9 $$e_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-44)+28}{2*36}=\frac{72}{72} =1 $
