Question

Express (a+2b)(3a+2c) as difference of two squares

Answer 1

Answer:

The answer is (2a+b+c)² - (b-a-c) ²

Explanation:

Qs: (a+2b) (3a+2c)

Or, {(a+2b) + (3a+2c) / 2}² - {(a+2b)-(3a+2c) / 2}

After applying formula we get,

{(4a+2b+2c) / 2}² - {2(b-a-c) / 2} ²

Or, {2(2a+b+c) / 2}² - {2(b-a-c) / 2}²

Or, (2a+b+c)² - (b-a-c)²
