Example 16 Find the following products using appropriate identities: (x + 3) (x + 3) (x + 3)(x + 3) = (x + 3)2 Using (a + b)2 = a2 + 2ab + b2 putting a = x, b = 3 = x2 + 2(x)(3) + (3)2 = x2 + 6x + 9 Example 16 Find the following products using appropriate identities: (ii) (x 3) (x + 5) (x 3) (x + 5) Using (x + a) (x + b) = x2 + (a + b)x + ab, putting a = 3, b = 5 = x2 + ( 3 + 5)x + ( 3)(5) = x2 + 2x 15
