$j (j + 3) = 0$

Step 1

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

$j = 0$

$j + 3 = 0$

Step 2

Set $j$ equal to $0$ .

$j = 0$

Step 3

Set $j + 3$ equal to $0$ and solve for $j$ .

Tap for more steps...

Set $j + 3$ equal to $0$ .

$j + 3 = 0$

Subtract $3$ from both sides of the equation.

$j = - 3$

Step 4

The final solution is all the values that make $j (j + 3) = 0$ true.

$j = 0, - 3$
