Algebra Examples

r (r - 10) = 0

$r (r - 10) = 0$

Step 1

If any individual factor on the left side of the equation is equal to

0

$0$ , the entire expression will be equal to

0

$0$ .

r = 0

$r = 0$

r - 10 = 0

$r - 10 = 0$

Step 2

Set

r

$r$ equal to

0

$0$ .

r = 0

$r = 0$

Step 3

Set

r - 10

$r - 10$ equal to

0

$0$ and solve for

r

$r$ .

Step 3.1

Set

r - 10

$r - 10$ equal to

0

$0$ .

r - 10 = 0

$r - 10 = 0$

Step 3.2

Add

10

$10$ to both sides of the equation.

r = 10

$r = 10$

r = 10

$r = 10$

Step 4

The final solution is all the values that make

r (r - 10) = 0

$r (r - 10) = 0$ true.

r = 0, 10

$r = 0, 10$

$r (r - 10) = 0$
