Question

Find the product of the following binomial using suitable identity
(x+2b) (x-2b)​

Answer 1

ANSWER✔

$\large\underline\bold{GIVEN,}$

$\sf\dashrightarrow (x+2b)(x-2b)$

$\large\underline\bold{SOLUTION,}$

$\large{\boxed{\bf{ \star\:\: (a+b)(a-b)= a^2-b^2\:\: \star}}}$

$\sf\implies (x+2b)(x-2b)$

$\sf\implies (x)^2-(2b)^2\:----[given\:identity]$

$\sf\implies x^2-4b^2$

$\large{\boxed{\bf{ \star\:\: x^2-4b^2\:\: \star}}}$

Answer 2

Answer:

$\huge\underline\bold\red{Answer!!}$

$(a + b)(a - b) = a {}^{2} - b {}^{2}$

$(x + 2b)(x - 2b)$

$(x {}^{2} ) - (2b) {}^{2} - - (given \: identity)$

$x {}^{2} - 4b {}^{2}$

answer = x² - 4b²
