expand (x+h(x)+1-(x+1))/(h(x))

expand

\frac{x + h ( x ) + 1 - ( x + 1 )}{h ( x )}

1

Solution steps

\frac{x + h ( x ) + 1 - ( x + 1 )}{h ( x )}

Remove parentheses:

(a) = a

= \frac{x + h x + 1 - ( x + 1 )}{h x}

Expand

x + h x + 1 - (x + 1) : x h

= \frac{x h}{x h}

Apply rule

\frac{a}{a} = 1

= 1

(u + v + w) (\frac{v + u + 1}{( u + v ) ^{2}})

d x (5 x^{2} + 2 x + 1)^{3} + ln (x + 1)

, x (1 + cot (x)) + cos (x) (1 - tan (x))

sin (t) - sin (t) u (t - 5)

(e^{- 7 x} - e^{- 3 x}) (\frac{5}{4})
