Q1 of 59 Page 263

Select a suitable identity and find the following products

(6x + 5) (6x + 6)

Given:(6x + 5) (6x + 6),it is a product of 2 binomial expressions which have the terms (6x + 5) and (6x + 6).

Now when we compare these expressions with the identities, we


find it in the form of (x + a)(x + b),where x = 6x and a = 5 and b = 6,


Thus,(x + a)(x + b) = x2 + x(b + a) + ab


Hence, (6x + 5) (6x + 6) = (6x)2 + 6x(5 + 6) + 30 = 12x2 + 66x + 30
