Question

Q3. Expansion of (2a+b)^2 is​

Answer 1

Answer:

(2a)²+b²+2(2a)(b)

Explanation:

using the formula of a+b whole square.

Answer 2

Expand:​  $(2a +b)^2$

To expand this given question, we can use the algebraic identity given below -

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

Expanding this using the identity, we get the answer as -

$(2a + b)^2 = (2a)^2 + 2 * 2a * b + (b)^2$

$= 4a^2 + 4ab + b^2$.
