4*10^2b-8+8=54
We move all terms to the left:
4*10^2b-8+8-(54)=0
We add all the numbers together, and all the variables
4*10^2b-54=0
Wy multiply elements
40b^2-54=0
a = 40; b = 0; c = -54;
Δ = b2-4ac
Δ = 02-4·40·(-54)
Δ = 8640
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}$$b_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{8640}=\sqrt{576*15}=\sqrt{576}*\sqrt{15}=24\sqrt{15}$$b_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-24\sqrt{15}}{2*40}=\frac{0-24\sqrt{15}}{80} =-\frac{24\sqrt{15}}{80} =-\frac{3\sqrt{15}}{10} $$b_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+24\sqrt{15}}{2*40}=\frac{0+24\sqrt{15}}{80} =\frac{24\sqrt{15}}{80} =\frac{3\sqrt{15}}{10} $
