-221=17(b+553)b=
We move all terms to the left:
-221-(17(b+553)b)=0
We calculate terms in parentheses: -(17(b+553)b), so:We get rid of parentheses
17(b+553)b
We multiply parentheses
17b^2+9401b
Back to the equation:
-(17b^2+9401b)
-17b^2-9401b-221=0
a = -17; b = -9401; c = -221;
Δ = b2-4ac
Δ = -94012-4·(-17)·(-221)
Δ = 88363773
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}$$b_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{88363773}=\sqrt{2601*33973}=\sqrt{2601}*\sqrt{33973}=51\sqrt{33973}$$b_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-9401)-51\sqrt{33973}}{2*-17}=\frac{9401-51\sqrt{33973}}{-34} $$b_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-9401)+51\sqrt{33973}}{2*-17}=\frac{9401+51\sqrt{33973}}{-34} $
