Question

Need an answer for expand and simplify bracket quickly please


`- 2(p - 4)(p + 4)`
​

Answer 1

`-p^2+32`

Explanation:

Start by expanding the
`-2` into the
`(p-4)` bracket using the distributive method:

`-2(p-4)\\-2p + 8`

Now, expand the result into the remaining bracket:

`(-2p + 8)(p+4)\\-2p^2 -8p+8p+32\\-2p^2 + 32`
