Write the factored form using these integers.
(x+6)(x+7)=0
(x+6)(x+7)=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+6=0
x+7=0
Set the first factor equal to 0 and solve.
Tap for more steps…
Set the first factor equal to 0.
x+6=0
Subtract 6 from both sides of the equation.
x=-6
x=-6
Set the next factor equal to 0 and solve.
Tap for more steps…
Set the next factor equal to 0.
x+7=0
Subtract 7 from both sides of the equation.
x=-7
x=-7
The final solution is all the values that make (x+6)(x+7)=0 true.
x=-6,-7
