4/x - x/8 = 0
----------
Begin by doing something.
Eliminate fractions.
Multiply by 8
32/x - x = 0
Multiply by x
32 - x^2 = 0
Any ideas yet?
================
Or,
4/x - x/8 = 0
4/x = x/8
Cross multiply
x^2 = 32

4%2Fx%22%22-%22%22x%2F8 %22%22=%22%22 %220%22


    4%2Fx %22%22=%22%22 x%2F8

Cross multiply:

      x%5E2%22%22=%22%2232

      x%22%22=%22%22%22%22+%2B-+sqrt%2832%29

      x%22%22=%22%22%22%22+%2B-+sqrt%2816%2A2%29

      x%22%22=%22%22%22%22+%2B-+4sqrt%282%29

Two solutions 4sqrt%282%29 and -4sqrt%282%29

4/x =x/8
multiply both sides by 8x
32=x^2
what is the square root of 32?
