Question

I don’t know the answer to the question

Answer 1

see explanation

Explanation:

P - G

= 8
`w^(4)` - 3w²z² +
`z^(4)` - ( - 3
`w^(4)` + 2w²z² + 5
`z^(4)` )

= 8
`w^(4)` + 2w²z² +
`z^(4)` + 3
`w^(4)` - 2w²z² - 5
`z^(4)`

Collect like terms

= (8
`w^(4)` + 3
`w^(4)` ) + (- 3w²z² - 2w²z² ) + (
`z^(4)` - 5
`z^(4)` )

= 11
`w^(4)` - 5w²z² - 4
`z^(4)`
