The difference between 2 integers is four, and the sum of two integers is sixteen. What is the absolute value of the difference of the squares of the integers?

 

Okay, ALL I can think of for this is guess and check. Is there a smarter method, and how?

You can make simple equations

\(x-y=4\)

\(x+y=16\)

 

Now solve... by elimination

 

\(2x=20\)

\(x=10\)

 

Now solve for y

\(10+y=16\)

\(y=6\)

 

So the difference between the squares of the integers is:

\(10^2-6^2=64\)

yeah, don't inhale accelerator.

 

and wash your hands after using superglue.

 

 

I learned the lesson by having a sudden bout of nausea and almost threw up.

a - b = 4,  a +b = 16, solve for a, b
a = 10  and   b=6
Abs[10^2 - 6^2] = 64
