Question

how do i simplify comlex fractions, like this one:

((5/x)-(x/x-1)) / ((x/x+1)+(6/x))

These are strains...you strain.

Start with the numerator
((5/x)-(x/x-1))

Multply by x(x-1)/x(x-1)

That simplifies it some.

Then the denominator:
multiply be x(x-1)/x(x-1)

See if that gets you somewhere. WATCH signs.

if iadd the square of a number to 2 times the number, i get 63. what could the number be?

i need help wit roman numerals asap
