How do you factor ax-xb-ay plus yb?
Recall distributivity a(b + c) = ab + ac = (b + c)a and associativity (ab)c = a(bc) (a + b) + c = a + (b + c) as well as commutativity ab = ba a + b = b + a we are gonna need those. See for yourself when I applied each to learn the trick: ax - bx - ay + yb = (ax - bx) + (-ay + yb) = x(a - b) + -y(a - b) = (x - y)(a - b)
Can a factor of a number be greater than the number?
No, unless you're factoring negative numbers. (For example, -36 = -1 x 36.) But a positive number cannot have a factor greater than it. The reason why is that if a larger number times something is a smaller (positive) number, that "something" must be between 0 and 1: a > b > 0 (where a and b are positive whole numbers) ax = b (for some x) Therefore, a > ax > 0. Dividing by a: 1 > x > 0, so x cannot be a whole number.
