d/((x+10))-d/((x-10))=4

解

\frac{d}{( x + 10 )} - \frac{d}{( x - 10 )} = 4

解

x = \frac{- 20 d + 400}{2}, x = - \frac{- 20 d + 400}{2}

解答ステップ

\frac{d}{( x + 10 )} - \frac{d}{( x - 10 )} = 4

LCMで乗じる

d (x - 10) - d (x + 10) = 4 (x + 10) (x - 10)

解く

d (x - 10) - d (x + 10) = 4 (x + 10) (x - 10) : x = \frac{- 20 d + 400}{2}, x = - \frac{- 20 d + 400}{2}

x = \frac{- 20 d + 400}{2}, x = - \frac{- 20 d + 400}{2}

0=(-x^3)/(((x+2)(x-1)))

0 = \frac{- x ^{3}}{( ( x + 2 ) ( x - 1 ) )}

(11)/(7x+1)= 41/2

\frac{11}{7 x + 1} = \frac{41}{2}

x/(4(2x-3))=6x+2

\frac{x}{4 ( 2 x - 3 )} = 6 x + 2

e(x)= 1/x-1/(|x|)

e (x) = \frac{1}{x} - \frac{1}{∣ x ∣}

(((1-x)^3(x+2)^4))/(((x+9)^2(x-8)))=0

\frac{( ( 1 - x ) ^{3} ( x + 2 ) ^{4} )}{( ( x + 9 ) ^{2} ( x - 8 ) )} = 0
