Step 24.1

Move ${(1 - 289 x^{2})}^{\frac{1}{2}}$ .

$\frac{- 17 ({(1 - 289 x^{2})}^{\frac{1}{2}} {(1 - 289 x^{2})}^{\frac{1}{2}}) - 289 \arccos (17 x) x \sqrt{1 - 289 x^{2}}}{{(1 - 289 x^{2})}^{1}}$

Step 24.2

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

Step 24.3

Combine the numerators over the common denominator.

$\frac{- 17 {(1 - 289 x^{2})}^{\frac{1 + 1}{2}} - 289 \arccos (17 x) x \sqrt{1 - 289 x^{2}}}{{(1 - 289 x^{2})}^{1}}$

Step 24.4

Add $1$ and $1$ .

$\frac{- 17 {(1 - 289 x^{2})}^{\frac{2}{2}} - 289 \arccos (17 x) x \sqrt{1 - 289 x^{2}}}{{(1 - 289 x^{2})}^{1}}$

Step 24.5

Divide $2$ by $2$ .

Step 27.2.1.1

Multiply $- 17$ by $1$ .

$\frac{- 17 - 17 (- 289 x^{2}) - 289 \arccos (17 x) x \sqrt{1 - 289 x^{2}}}{1 - 289 x^{2}}$

Step 27.2.1.2

Multiply $- 289$ by $- 17$ .

$\frac{- 17 + 4913 x^{2} - 289 \arccos (17 x) x \sqrt{1 - 289 x^{2}}}{1 - 289 x^{2}}$

Step 27.2.1.3

Rewrite $1$ as $1^{2}$ .

$\frac{- 17 + 4913 x^{2} - 289 \arccos (17 x) x \sqrt{1^{2} - 289 x^{2}}}{1 - 289 x^{2}}$

Step 27.2.1.4

Rewrite $289 x^{2}$ as ${(17 x)}^{2}$ .

$\frac{- 17 + 4913 x^{2} - 289 \arccos (17 x) x \sqrt{1^{2} - {(17 x)}^{2}}}{1 - 289 x^{2}}$

Step 27.2.1.5

Since both terms are perfect squares, factor using the difference of squares formula, $a^{2} - b^{2} = (a + b) (a - b)$ where $a = 1$ and $b = 17 x$ .

$\frac{- 17 + 4913 x^{2} - 289 \arccos (17 x) x \sqrt{(1 + 17 x) (1 - (17 x))}}{1 - 289 x^{2}}$

Step 27.2.1.6

Multiply $17$ by $- 1$ .

$\frac{- 17 + 4913 x^{2} - 289 \arccos (17 x) x \sqrt{(1 + 17 x) (1 - 17 x)}}{1 - 289 x^{2}}$

Step 27.2.2

Reorder factors in $- 17 + 4913 x^{2} - 289 \arccos (17 x) x \sqrt{(1 + 17 x) (1 - 17 x)}$ .

$\frac{- 17 + 4913 x^{2} - 289 x \arccos (17 x) \sqrt{(1 + 17 x) (1 - 17 x)}}{1 - 289 x^{2}}$

Step 27.3

Reorder terms.

$\frac{4913 x^{2} - 289 x \sqrt{(1 + 17 x) (1 - 17 x)} \arccos (17 x) - 17}{- 289 x^{2} + 1}$
