limit as x approaches 1 of (2x+1)(x-1)

x \to 1 lim ((2 x + 1) (x - 1))

0

Solution steps

x \to 1 lim ((2 x + 1) (x - 1))

Plug in the value

x = 1

= (2 \cdot 1 + 1) (1 - 1)

Simplify

= 0

\int \frac{5}{x} - \frac{3}{x ^{2}} d x

\frac{1}{3} x^{3} - \frac{7}{2} x^{2} - 8 x + 3

\int e^{1 - 6 t} d t

(x^{3} - 7 x + 2) (2 x^{4} - 1)

x \to 1 lim (1 - x^{3})
