Question #6d96f

Answer 1

`4x^2 +2x + 0.25`

Explanation:

First you need to understand that `(2x+1/2)^2` is the same as

`(2x+1/2)(2x+1/2)`

Then we multiply out the brackets;

`color(red)(2x xx 2x) + color(blue)(x + x) + color(green)(1/2 xx 1/2)`

`color(red)(4x^2) + color(blue)(2x) + color(green)(0.25)`
