Question

factorize (a+2b)²-a²​

Answer 1

Step-by-step explanation:

(a + 2b)2 – a2 = ( a + 2b)2 – (a)2

= (a + 2b + a) (a + 2b – a)

= (2a + 2b) (2b)

= 2 (a + b) (2b)

= 2 × 2b (a + b)

= 4b (a + b)

Answer 2

Answer:

4b (a+b)

Step-by-step explanation:

(a+2b)²-a²

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

= (2a+2b)(2b)

= 2b×(2a+2b)

= 4b (a+b)
