limit as x approaches 3-of (x^2-9)/(x-3)

x \to 3 - lim (\frac{x ^{2} - 9}{x - 3})

6

Solution steps

x \to 3 - lim (\frac{x ^{2} - 9}{x - 3})

Simplify

\frac{x ^{2} - 9}{x - 3} : x + 3

= x \to 3 - lim (x + 3)

Plug in the value

x = 3

= 3 + 3

Simplify

= 6

\frac{\partial}{\partial y} (cos (n x) e^{n y})

\int \frac{9}{x ^{2} x ^{2} + 36} d x

\int sin (4 x) sin (2 x) d x

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

\frac{x ^{3} + 3 x}{x ^{2} - 4 x + 3}
