Question

factorise the above sum by splitting the middle term or by using identities​

Answer 1

Answer:

=(x + 8y)(x)

EXPLANATION:

$(x + 4y)^{2} - 16y^{2}$

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

$a = (x + 4y)$

$b = (4y)$

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

putting the value of a & b

$(x + 4y)^{2} - 16y^{2} = (x + 4y + 4y)(x + 4y - 4y)$

                          $=(x + 8y)(x)$
