for the following two numbers, find two factors of the first number such that their product is the first number and their sum is
zepelin [54]
You can make some algebraic equations and solve it.
The first would be:
x \times y =  - 21
The second would be
x + y =  - 4
You can then rearrange the second into
x =  - 4 - y
And subsitute it into the first like so:
( - y - 4) \times y = -  21
After that, distribute the y into the parantheses.
{ - y}^{2}  - 4y =  - 21
Subtract the 21 on both sides and multiply by -1 on both sides:
{ - y}^{2}  - 4y  +  21 \\ {y}^{2}  + 4y  -  21
You then can factor it into:
(y + 3) \times (y - 7) = 0
With Zero Product Property, we can determine y to be either -3 and 7. Since the variables are interchangable, you can say the same about x, just that whatever x is, y must be the other value.


Thus, the answer is 7 and -3.
