 Example: Express 9a2 + 15ab as product of factors. Solution: To find factors first we find HCF of the terms, that is Breaking each monomial simplest numerical literal factors, we get 9a2 = 3 * 3 * a * a 15ab = 3 * 5 * a * b HCF of the terms = 3 * a = 3a 9a2 + 15ab = 3a * 3a + 3a * 5b (Since 3a is the HCF) = 3a(3a + 5b) Directions: Write the given terms as product of factors. Also write at least 10 examples of your own.
