Question

find the product: (2a+y) (2a-y) (4a^2+y^2)​

Answer 1

Answer:

here, we can see that

(2a+y)(2a-y)

is written in the form

(a+b)(a-b)=

${a}^{2} - {b}^{2}$

so

${4a}^{2} - {y}^{2}$

now the equation is again in that form

$({(4a)}^{2} + {y}^{2} )( {4a}^{2} - {y}^{2} ) \\ ( {4a}^{4} - y4) \\ \\ = {16a}^{4} - {y}^{4}$

hence, this is your anser

have a great day ahead!
