1. simple math question

hi friends ,

If the difference of two numbers is 8 and their product is 12, what is the sum of their squares?

There is no possible answer for this...You told their product is 12. So the possible combination is (1,12),(2,6),(3,4)

Whether the number is +ve or -ve, there is no possible for getting the difference 8.

If i am wrong then correct me...otherwise correct your question...

hi suresh .

i was given that question by an interview . i also confused with question . still i don't know correct answer . As u told question may be wrong i accept it ..

It is given that a -b = 8
and ab = 12

we need to calculate a^2 + b^2

We know that a^2 + b^2 = (a-b)^2 + 2ab
= 8^2 + 2 *12
= 88

To Suresh, It is not given that both a and b are integers and you are not asked to find the values of a and b.

Hope this helps you guys.

hi james,

Nice explanation. Now i am clear about the question....
