G(x)=-8/(x-5)

解

G (x) = - \frac{8}{x - 5}

x = \frac{5 G + 25 G ^{2} - 32 G}{2 G}, x = \frac{5 G - 25 G ^{2} - 32 G}{2 G}; G \neq = 0

解答ステップ

G (x) = - \frac{8}{x - 5}

以下で両辺を乗じる:

x - 5

G x (x - 5) = - 8

解く

G x (x - 5) = - 8 : x = \frac{5 G + 25 G ^{2} - 32 G}{2 G}, x = \frac{5 G - 25 G ^{2} - 32 G}{2 G}; G \neq = 0

x = \frac{5 G + 25 G ^{2} - 32 G}{2 G}, x = \frac{5 G - 25 G ^{2} - 32 G}{2 G}; G \neq = 0
