Answer:
You chose the correct option on the picture
x = -4; x = 12
Explanation:
You solve for x by simplifying both sides of the equation, then isolating the variable.
If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.
x + 4 = 0
x − 12 = 0
Set x + 4 equal to 0 and solve for x.
Set x+4 equal to 0.
x+4=0
Subtract 4 from both sides of the equation.
x = −4
Set x − 12 equal to 0 and solve for x.
Set x−12 equal to 0.
x−12=0
Add 12 to both sides of the equation.
x=12
The final solution is all the values that make (x+4)(x−12)=0 true.
x=−4,12
Sorry for taking a while but have a good day
