What are two numbers that have a product of 15 but also a sum of 8

3 and 5

Step-by-step explanation:

3+5=8, and also

3x5=15

3 and 5

Hope this helps!!!

Step-by-step explanation:

Begin by creating the two equations that are provided by the information in the question.

x + y = 8

and

x y = 15

Now you can solve logically because of the simplicity of the numbers, by listing the factors of 15 and determine which pair will add up to 8

1 and 15

3 and 5

And Then The Answer is 3 and 5

Or you can solve algebraically by substitution

x + y = 8  can be converted to

y = 8 − x

Now substitute the first equation into the second equation for the y variable.

x ( 8 − x ) = 15

Distribute

8 x −x 2 = 15  

Set the equation equal to zero.

8 x − x 2 − 15 = 15 − 15

Rearrange to put the squared term first.

− x 2 + 8 x − 15=0

-1(x-5)(x-3) = 0#

Set both factors equal to zero.

x − 5 = 0  

x = 5

x− 3 = 0

x = 3

5 and 3
