2/x-4 + 1 divided by x + 4/x-4
Complex fraction made of sums involving rational expressions... i dont get this:(
Always learn to use brackets to make yourself very clear as to what you want done. Because:
2/x-4 + 1 divided by x + 4/x-4 could mean: 2/ (x-4) +1 / x + (4/x) -4, or:
2/ [x-4 + 1] / x + [4/x - 4]......etc.
