Example: Express 15x^{2}y^{2} + 6x^{2}yz + 9xyz 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 15x^{2}y^{2} = 3 * 5 * x * y 6x^{2}yz = 3 * 2 * x * y * z 9xyz = 3 * 3 * x * y * z HCF of the terms = 3 * x * y = 3xy 15x^{2}y^{2} + 6x^{2}yz + 9xyz = 3xy * 5xy + 3xy * 2z + 3xy * 3z (Since 3xy is the HCF) = 3xy(5xy + 2x + 3z) Directions: Write the given terms as product of factors.
