Question

How do you write `(4m+8)^2` in standard form?

Answer 1

`16m^2 + 64m + 64`

Explanation:

Start by Writing `(4m + 8)` twice
`(4m+8)^2 = (4m + 8)(4m+8)`

Each Term in the first parenthesis is to be distributed into the second parenthesis.
`= 4m(4m + 8) + 8(4m + 8)`
`= 16m^2 + 32m + 32m + 64`
`= 16m^2 + 64m + 64`
