3 Answers
Explanation:
STEP ONE: Add
STEP TWO: Factor the equation! Two number that equal
THEREFORE,
Explanation:
First, we turn the equation so that it equals zero.
Let's see whether we could factor this.
We find the factors for 24:
1,24
2,12
3,8
4,6
-1,-24
-2,-12
-3,-8
-4,-6
We see that -3 and -8 add up to -11.
Therefore,
Therefore, our answers are 3 and 8.
You could have used the quadratic formula, but it is unnecessary in this case.
Explanation:
Rearrange the equation so it becomes a standard form quadratic equation,
#a=1# #b=-11# #c=24#
Plug those values into the quadratic formula:
