Solve for c (c+4)(c+5)=0

$(c + 4) (c + 5) = 0$

Step 1

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

$c + 4 = 0$

$c + 5 = 0$

Step 2

Set $c + 4$ equal to $0$ and solve for $c$ .

Set $c + 4$ equal to $0$ .

$c + 4 = 0$

Subtract $4$ from both sides of the equation.

$c = - 4$

Step 3

Set $c + 5$ equal to $0$ and solve for $c$ .

Set $c + 5$ equal to $0$ .

$c + 5 = 0$

Subtract $5$ from both sides of the equation.

$c = - 5$

Step 4

The final solution is all the values that make $(c + 4) (c + 5) = 0$ true.

$c = - 4, - 5$
