Question

Use a suitable identity to get each of the following products.
(i) (x + 9) (x + 9)
(ii) (3y + 9) (3y + 9)
(iii) (3a – 5) (3a – 5)
(iv) (3x – 5) (3x + 5)​

Answer 1

Answer:

(i) (a+b)^2=a^2+2ab+b^2

(ii) Same as (i)

(iii) (a-b)^2=a^2-2ab+b^2

(iv) (a-b)(a+b)=(a-b)^2

Step-by-step explanation:

I don't have much time. So,Use the following identities and solve product of each.
