limit as x approaches-2 of (x^2-1)/(2-x)

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

\frac{3}{4}

Decimal Notation

0.75

Solution steps

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

Plug in the value

x = - 2

= \frac{( - 2 ) ^{2} - 1}{2 - ( - 2 )}

Simplify

\frac{( - 2 ) ^{2} - 1}{2 - ( - 2 )} : \frac{3}{4}

= \frac{3}{4}

y = x, (25, 5)

\frac{d ^{2}}{d x ^{2}} (\frac{x ^{2} - 1}{x ^{2} + 1})

\frac{d}{d x} (\frac{1}{π} c x^{2} + ln (cos^{3} (x)))

\int_{1}^{9} \frac{1}{6 - x} d x
