Answer:
Factor x²−6x−27 using the AC method.
(x−9)(x+3)=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−9=0
x+3=0
Set x−9
equal to 0 and solve for x.
x=9
Set x+3 equal to 0 and solve for x.
x=−3
The final solution is all the values that make (x−9)(x+3)=0 true.
x=9,−3
