Question

Use suitable identities to find the squares.
(i) (a+2b)^2

(ii) (3x-2)^2

I will mark u as brainliest those who will answer this correctly​

Answer 1

Answer:

(a + 2b)^2 = a^2 + 4ab + 4b^2

(3x - 2)^2 = 9x^2 - 12x + 4

Step-by-step explanation:

Answer 2

By using (a+b)² = a²+b²+2ab

(i) (a+2b)² = a²+4b²+4ab

By using (a-b)² = a²+b²-2ab

(ii) (3x-2)² = 9x²+4 - 12x
