Find two numbers whose sum is 15 and the product is 36

The two numbers are 3 and 12.

I got these numbers by factoring 36.

1 * 36 sum : 37

2 * 18 sum : 20

3 * 12 sum : 15

It is easier to find the factor of a number and solve for the sum. Than to find the addends of a number and solve for the product.

There are 9 factors of 36 while 14 addends of 15.

OK so if you're wanting 15 and 36 you will need to know what goes into each of them but if you just need 15 then let's try to find that one so, what does go into 15 well let's find out.

15:1*15,3*5

36:1*36,2*18,3*12,4*9,6²

so, based on what we have here there are a lot of answers between numbers 15&36 but one maybe two or more answers for what can go into 15 and 36.

3*12=36

12+3=15

so, the two numbers you need are 3 and 12.
