$f (x) = \frac{x^{2} - 7 x (a + h) x^{2} - 7 x a}{h}$

Step 1

Factor $x$ out of $x^{2} - 7 x (a + h) x^{2} - 7 x a$ .

Tap for more steps...

Step 1.1

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

$f (x) = \frac{x \cdot x - 7 x (a + h) x^{2} - 7 x a}{h}$

Step 1.2

Factor $x$ out of $- 7 x (a + h) x^{2}$ .

$f (x) = \frac{x \cdot x + x ((- 7 (a + h)) x^{2}) - 7 x a}{h}$

Step 1.3

Factor $x$ out of $- 7 x a$ .

$f (x) = \frac{x \cdot x + x ((- 7 (a + h)) x^{2}) + x (- 7 a)}{h}$

Step 1.4

Factor $x$ out of $x \cdot x + x ((- 7 (a + h)) x^{2})$ .

$f (x) = \frac{x (x + (- 7 (a + h)) x^{2}) + x (- 7 a)}{h}$

Step 1.5

Factor $x$ out of $x (x + (- 7 (a + h)) x^{2}) + x (- 7 a)$ .

$f (x) = \frac{x (x + (- 7 (a + h)) x^{2} - 7 a)}{h}$

Step 2

Apply the distributive property.

$f (x) = \frac{x (x + (- 7 a - 7 h) x^{2} - 7 a)}{h}$

Step 3

Apply the distributive property.

$f (x) = \frac{x (x - 7 a x^{2} - 7 h x^{2} - 7 a)}{h}$
