Solve by Factoring x^3-10x^2+24x=0

$x^{3} - 10 x^{2} + 24 x = 0$

Step 1

Factor $x$ out of $x^{3} - 10 x^{2} + 24 x$ .

Factor $x$ out of $x^{3}$ .

$x \cdot x^{2} - 10 x^{2} + 24 x = 0$

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

$x \cdot x^{2} + x (- 10 x) + 24 x = 0$

Factor $x$ out of $24 x$ .

$x \cdot x^{2} + x (- 10 x) + x \cdot 24 = 0$

Factor $x$ out of $x \cdot x^{2} + x (- 10 x)$ .

$x (x^{2} - 10 x) + x \cdot 24 = 0$

Factor $x$ out of $x (x^{2} - 10 x) + x \cdot 24$ .

$x (x^{2} - 10 x + 24) = 0$

Step 2

Factor.

Factor $x^{2} - 10 x + 24$ using the AC method.

Consider the form $x^{2} + b x + c$ . Find a pair of integers whose product is $c$ and whose sum is $b$ . In this case, whose product is $24$ and whose sum is $- 10$ .

$- 6, - 4$

Write the factored form using these integers.

$x ((x - 6) (x - 4)) = 0$

Remove unnecessary parentheses.

$x (x - 6) (x - 4) = 0$

Step 3

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

$x = 0$

$x - 6 = 0$

$x - 4 = 0$

Step 4

Set $x$ equal to $0$ .

$x = 0$

Step 5

Set $x - 6$ equal to $0$ and solve for $x$ .

Set $x - 6$ equal to $0$ .

$x - 6 = 0$

Add $6$ to both sides of the equation.

$x = 6$

Step 6

Set $x - 4$ equal to $0$ and solve for $x$ .

Set $x - 4$ equal to $0$ .

$x - 4 = 0$

Add $4$ to both sides of the equation.

$x = 4$

Step 7

The final solution is all the values that make $x (x - 6) (x - 4) = 0$ true.

$x = 0, 6, 4$
