1) First is an odd function because f(-x)=-f(x)
3) 3d is an even function because f(-x)=f(x)
2) 2d looks like sin function and it is also odd.

X2y4(x2 - 16) - 9y4(x4 - 16) how do i simply this?

e-lub [12.9K]

Answer:

The simplified expression is given as

$8x^2y^4(17x^2-2)$

Step-by-step explanation:

step one:

Given the expression

$x^2y^4(x^2 - 16) - 9y^4(x^4 - 16)$

step two:

First, let us open the bracket we have

$x^2y^4(x^2 - 16) - 9y^4(x^4 - 16)\\\\x^4y^4-16x^2y^4-9x^4y^4+144x^4y^4\\\\$

step three:

collect like terms we have

$x^4y^4-16x^2y^4-9x^4y^4+144x^4y^4\\\\x^4y^4-9x^4y^4+144x^4y^4-16x^2y^4\\\\-8x^4y^4+144x^4y^4-16x^2y^4\\\\136x^4y^4-16x^2y^4\\\\\\$

step four:

we can now factor out $8x^2y^4$ we have

$8x^2y^4(17x^2-2)$
