roots (a+x)/(a^2+x^2)

roots

\frac{a + x}{a ^{2} + x ^{2}}

x = - a

Solution steps

\frac{a + x}{a ^{2} + x ^{2}}

The roots are the intercepts with the x-axis

(y = 0)

\frac{a + x}{a ^{2} + x ^{2}} = 0

\frac{f ( x )}{g ( x )} = 0 \Rightarrow f (x) = 0

a + x = 0

Move

a

to the right side

x = - a

2 x - 1

x \to 0 lim (\frac{1}{∣ x ∣})

- 2 x^{2} + 8, 3 x + 1, x = 2, x = 0

f (x) = 2 x e^{x} + e^{x} x^{2}

x \to 0 lim (x^{\frac{1}{3}})
