How do I simplify this 1/x - 1/b over 1/xb + 1/2
:
1%2Fx+-+1%2Fb
---------- =
1%2F%28xb%29+%2B+1%2F2
:
Convert the fractions into a single fraction with a common denominator
%28%28b-x%29%29%2F%28xb%29
---------- =
%28%282%2B%28xb%29%29%29%2F%282xb%29
:
Remember when you divide fractions, you invert the dividing fraction and mult:
%28%28b-x%29%29%2F%28xb%29 * %282xb%29%2F%28%282%2Bxb%29%29 = %28%28b-x%29%29%2F1 * %282%29%2F%28%282%2Bxb%29%29 = %282%28b-x%29%29%2F%28%282+%2B+xb%29%29; canceled the xb's
