How do you factor Ab plus CD - cb - ad?
Well, honey, first things first, you group the terms with common variables together. So, you have (Ab - ad) + (CD - cb). Then, you factor out the common factors from each group. That gives you A(b - d) + C(D - b). Voila! That's your factored expression.
What is the greatest common factor of 27ab and 81b?

Is the difference of two rational numbers always a rational number?
Yes. Since they are rational numbers, let's call the first one a/b and the second one c/d where a,b,c, and d are integers. Now we can subtract by finding a common denominator. Let's use bd. So we have ad/bd-cb/bc= (ad-bc)/CD which is rational since we know ad and bc are integers being the product of integers and CD is also an integers. Call ad-bd=P and call CD=Q where P and Q are integers. We now see the difference is of two rationals is rational.
