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
Step-by-step explanation:
For this case we have that David drew the cards given by:
We have:
Where "x" represents the sum of the cards that David drew.
To add, we first group similar terms:
Taking into account that equal signs are added and the same sign is placed, we have:
Taking into account that different signs are subtracted and the sign of the major is placed, we have:
Thus, the sum of David's three cards is
