simplify 3(x+1/x)

Solution

simplify

3 (x + \frac{1}{x})

\frac{3 ( x ^{2} + 1 )}{x}

Solution steps

3 (x + \frac{1}{x})

Join

x + \frac{1}{x} : \frac{x ^{2} + 1}{x}

= 3 \cdot \frac{x ^{2} + 1}{x}

Apply the fraction rule:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{3 ( x ^{2} + 1 )}{x}

a (n + 1) - b (n + 1) - n - 1

3 cos (x) + 3 sin (x) tan (x)

(- 1 + i) (2 + 3 i)

\frac{\frac{x ^{2} + 9 x + 18}{x ^{2} + 6 x + 8}}{\frac{x ^{2} - 3 x - 18}{x ^{2} + 2 x - 8}}

\frac{3 a ^{3} - 75 a}{a ( a + 5 ) ( a + 5 )}
