limit as x approaches 1 of (x^{3a}-3ax+3a-1)/((x-1)^2)

x \to 1 lim (\frac{x ^{3 a} - 3 a x + 3 a - 1}{( x - 1 ) ^{2}})

\frac{3 a ( 3 a - 1 )}{2}

Solution steps

x \to 1 lim (\frac{x ^{3 a} - 3 a x + 3 a - 1}{( x - 1 ) ^{2}})

Apply L'Hopital's Rule

: x \to 1 lim (\frac{3 a x ^{3 a - 1} - 3 a}{2 ( x - 1 )})

= x \to 1 lim (\frac{3 a x ^{3 a - 1} - 3 a}{2 ( x - 1 )})

Apply L'Hopital's Rule

: x \to 1 lim (\frac{3 a x ^{3 a - 2} ( 3 a - 1 )}{2})

= x \to 1 lim (\frac{3 a x ^{3 a - 2} ( 3 a - 1 )}{2})

Plug in the value

x = 1

= \frac{3 a \cdot 1 ^{3 a - 2} ( 3 a - 1 )}{2}

Simplify

= \frac{3 a ( 3 a - 1 )}{2}

\frac{d}{d t} (4 t^{2} + 3 t - 10)

13 e^{x^{2}}

y^{^{'}} + 3 y = 4

- y^{^{'}} x + y = - 7 x
