Question

(2x+1)2 solve using identities​

Answer 1

Solution:-

Identity used is :-

$\small\fbox\green{(a+b)²=(a)²+2(ab)+(b)²}$

So,

using the above formula we get as,

______________________________________

$(2x + 1) {}^{2} \\ \\ (2x) {}^{2} + 2(2x \times 1) + (1) {}^{2} \\ \\ = 4x {}^{2} + 4x + 1$

______________________________________

Hence,

The solution to the given question is :-

$\small\fbox\pink{4x²+4x+1}$
