Question

(x²+3)²-16y² factorise​

Answer 1

Answer:

The given expression is factorised below :

Step-by-step explanation:

Formula :

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

(x^2 + 3)^2 - (4y)^2

(x^2 + 4y + 3)(x^2 - 4y + 3)

Answer 2

Step-by-step explanation:

Using identity,

${x}^{2} - {y}^{2} = (x + y)(x - y)$

By use of this identity

${( {x}^{2} + 3)}^{2} - {(4y)}^{2}$

$( {x}^{2} + 3 + 4y)( {x}^{2} + 3 - 4y)$
