Step 1.1

Factor

$3$ out of

$3 x^{\frac{3}{2}}$ .

$3 (x^{\frac{3}{2}}) - 9 x^{\frac{1}{2}} + 6 x^{- \frac{1}{2}}$

Step 1.2

Factor

$3$ out of

$- 9 x^{\frac{1}{2}}$ .

$3 (x^{\frac{3}{2}}) + 3 (- 3 x^{\frac{1}{2}}) + 6 x^{- \frac{1}{2}}$

Step 1.3

Factor

$3$ out of

$6 x^{- \frac{1}{2}}$ .

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

Step 1.4

Factor

$3$ out of

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

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

Step 1.5

Factor

$3$ out of

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

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

Step 2

Rewrite the expression using the negative exponent rule

$b^{- n} = \frac{1}{b^{n}}$ .

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

Step 3

Combine

$2$ and

$\frac{1}{x^{\frac{1}{2}}}$ .

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