Simplify (5/x+6)/(25/(x^2)-36)

$\frac{\frac{5}{x} + 6}{\frac{25}{x^{2}} - 36}$

Step 1

Multiply the numerator and denominator of the complex fraction by $x^{2}$ .

Multiply $\frac{\frac{5}{x} + 6}{\frac{25}{x^{2}} - 36}$ by $\frac{x^{2}}{x^{2}}$ .

$\frac{x^{2}}{x^{2}} \cdot \frac{\frac{5}{x} + 6}{\frac{25}{x^{2}} - 36}$

Combine.

$\frac{x^{2} (\frac{5}{x} + 6)}{x^{2} (\frac{25}{x^{2}} - 36)}$

Step 2

Apply the distributive property.

$\frac{x^{2} \frac{5}{x} + x^{2} \cdot 6}{x^{2} \frac{25}{x^{2}} + x^{2} \cdot - 36}$

Step 3

Simplify by cancelling.

Cancel the common factor of $x$ .

Factor $x$ out of $x^{2}$ .

$\frac{x \cdot x \frac{5}{x} + x^{2} \cdot 6}{x^{2} \frac{25}{x^{2}} + x^{2} \cdot - 36}$

Cancel the common factor.

$\frac{x \cdot x \frac{5}{x} + x^{2} \cdot 6}{x^{2} \frac{25}{x^{2}} + x^{2} \cdot - 36}$

Rewrite the expression.

$\frac{x \cdot 5 + x^{2} \cdot 6}{x^{2} \frac{25}{x^{2}} + x^{2} \cdot - 36}$

Cancel the common factor of $x^{2}$ .

Cancel the common factor.

$\frac{x \cdot 5 + x^{2} \cdot 6}{x^{2} \frac{25}{x^{2}} + x^{2} \cdot - 36}$

Rewrite the expression.

$\frac{x \cdot 5 + x^{2} \cdot 6}{25 + x^{2} \cdot - 36}$

Step 4

Simplify the numerator.

Factor $x$ out of $x \cdot 5 + x^{2} \cdot 6$ .

Factor $x$ out of $x \cdot 5$ .

$\frac{x (5) + x^{2} \cdot 6}{25 + x^{2} \cdot - 36}$

Factor $x$ out of $x^{2} \cdot 6$ .

$\frac{x (5) + x (x \cdot 6)}{25 + x^{2} \cdot - 36}$

Factor $x$ out of $x (5) + x (x \cdot 6)$ .

$\frac{x (5 + x \cdot 6)}{25 + x^{2} \cdot - 36}$

Move $6$ to the left of $x$ .

$\frac{x (5 + 6 x)}{25 + x^{2} \cdot - 36}$

Step 5

Simplify the denominator.

Rewrite $25$ as $5^{2}$ .

$\frac{x (5 + 6 x)}{5^{2} + x^{2} \cdot - 36}$

Rewrite $- x^{2} \cdot - 36$ as ${(6 x)}^{2}$ .

$\frac{x (5 + 6 x)}{5^{2} - {(6 x)}^{2}}$

Since both terms are perfect squares, factor using the difference of squares formula, $a^{2} - b^{2} = (a + b) (a - b)$ where $a = 5$ and $b = 6 x$ .

$\frac{x (5 + 6 x)}{(5 + 6 x) (5 - (6 x))}$

Multiply $6$ by $- 1$ .

$\frac{x (5 + 6 x)}{(5 + 6 x) (5 - 6 x)}$

Step 6

Cancel the common factor of $5 + 6 x$ .

Cancel the common factor.

$\frac{x (5 + 6 x)}{(5 + 6 x) (5 - 6 x)}$

Rewrite the expression.

$\frac{x}{5 - 6 x}$

Simplify (5/x+6)/(25/(x^2)-36)
