Question

Could someone check my answer?

Answer 1

One positive number is 8 more than another. The sum of their squares is 104. Find both numbers.

Answer 2

(This is a quadratic equation!)

Answer 3

I used the equation \[x ^{2}+(x+8)^{2}=104\] and got x=-5 and x=4 as my two solutions.

Answer 4

I solved this by factoring, not using the formula, btw.
