My cousin approached me with a math question from her homework and it's got me stumped. Just wondering if any of you guys are maths wizards and could help.

Find two numbers whose sum is 10 and multiply together to equal 10.

The numbers aren't whole numbers. The answer is (rounded to 3 decimal places) 8.873 and 1.127

Yes, but usually they want you to show your working:

We get simultaneous equations:
Y+Z=10 and
Y x Z=10

Merging and multiply by Y gives
Y^2 -10Y -10= 0

Using [ -b+\- √(b^2 - 4ac)]÷2a gives

5 +\- √15

First you have to understand that "maths" is plural not singular.

Hey! Leave me out of this!
I can do maths as good as any 10 year old. (providing I have a calculator)
