limit as x approaches-4 of (x^2+5x+4)/(x^2+3x-4)

x \to - 4 lim (\frac{x ^{2} + 5 x + 4}{x ^{2} + 3 x - 4})

\frac{3}{5}

Decimal

0.6

Solution steps

x \to - 4 lim (\frac{x ^{2} + 5 x + 4}{x ^{2} + 3 x - 4})

Simplify

\frac{x ^{2} + 5 x + 4}{x ^{2} + 3 x - 4} : \frac{x + 1}{x - 1}

= x \to - 4 lim (\frac{x + 1}{x - 1})

Plug in the value

x = - 4

= \frac{- 4 + 1}{- 4 - 1}

Simplify

= \frac{3}{5}

\int_{- 1}^{1} x^{- 2} d x

\frac{d}{d x} (\frac{( 4 x )}{( x + 1 ) ^{2}})

x \to 1 lim (∣ 3 x - 6 ∣)

\int_{0}^{0.5} arccos (x) d x

n = 0 \sum \infty 7 (\frac{1}{10})^{n}
