Question

Expand the following using suitable identities (algebraic expressions)
$\pi$
​

Answer 1

Answer:

by using identify you can solve it

Answer 2

Answer:

$(2m + \frac{1}{4} )(2m + \frac{1}{4} )$

using the identity

(a+b)(a+b)=a²+b²

here

a=2m

b=1/4

therefore

${(2m)}^{2} + ( \frac{1}{4} )^{2} \\ 4 {m}^{2} + \frac{1}{16}$

therefore the answer is 4m²+1/16

hope it helps
