Find the x and y Intercepts f(x)=(5x^2-10x)/(4x-8)

$f (x) = \frac{5 x^{2} - 10 x}{4 x - 8}$

Step 1

Find the x-intercepts.

To find the x-intercept(s), substitute in $0$ for $y$ and solve for $x$ .

$0 = \frac{5 x^{2} - 10 x}{4 x - 8}$

Solve the equation.

Set the numerator equal to zero.

$5 x^{2} - 10 x = 0$

Solve the equation for $x$ .

Factor $5 x$ out of $5 x^{2} - 10 x$ .

Factor $5 x$ out of $5 x^{2}$ .

$5 x (x) - 10 x = 0$

Factor $5 x$ out of $- 10 x$ .

$5 x (x) + 5 x (- 2) = 0$

Factor $5 x$ out of $5 x (x) + 5 x (- 2)$ .

$5 x (x - 2) = 0$

If any individual factor on the left side of the equation is equal to $0$ , the entire expression will be equal to $0$ .

$x = 0$

$x - 2 = 0$

Set $x$ equal to $0$ .

$x = 0$

Set $x - 2$ equal to $0$ and solve for $x$ .

Set $x - 2$ equal to $0$ .

$x - 2 = 0$

Add $2$ to both sides of the equation.

$x = 2$

The final solution is all the values that make $5 x (x - 2) = 0$ true.

$x = 0, 2$

Exclude the solutions that do not make $0 = \frac{5 x^{2} - 10 x}{4 x - 8}$ true.

$x = 0$

x-intercept(s) in point form.

x-intercept(s): $(0, 0)$

Step 2

Find the y-intercepts.

To find the y-intercept(s), substitute in $0$ for $x$ and solve for $y$ .

$y = \frac{5 {(0)}^{2} - 10 \cdot 0}{4 (0) - 8}$

Solve the equation.

Remove parentheses.

$y = \frac{5 \cdot 0^{2} - 10 \cdot 0}{4 (0) - 8}$

Remove parentheses.

$y = \frac{5 {(0)}^{2} - 10 \cdot 0}{4 (0) - 8}$

Simplify $\frac{5 {(0)}^{2} - 10 \cdot 0}{4 (0) - 8}$ .

Simplify the numerator.

Raising $0$ to any positive power yields $0$ .

$y = \frac{5 \cdot 0 - 10 \cdot 0}{4 (0) - 8}$

Multiply $5$ by $0$ .

$y = \frac{0 - 10 \cdot 0}{4 (0) - 8}$

Multiply $- 10$ by $0$ .

$y = \frac{0 + 0}{4 (0) - 8}$

Add $0$ and $0$ .

$y = \frac{0}{4 (0) - 8}$

Simplify the denominator.

Multiply $4$ by $0$ .

$y = \frac{0}{0 - 8}$

Subtract $8$ from $0$ .

$y = \frac{0}{- 8}$

Divide $0$ by $- 8$ .

$y = 0$

y-intercept(s) in point form.

y-intercept(s): $(0, 0)$

Step 3

List the intersections.

x-intercept(s): $(0, 0)$

y-intercept(s): $(0, 0)$

Step 4

Find the x and y Intercepts f(x)=(5x^2-10x)/(4x-8)
