Answer 1

`-3i-2`

Explanation:

A conjugate of an expression in the form of `a+bi` is `a-bi`, and vice-versa.

So, here we got: `-2+3i`

`=3i-2`

Therefore, its conjugate will be `-3i-2`.

Answer 2

`-2-3i`

Explanation:

`"given a complex number "x+-yi`

`"then the conjugate is "xcolor(red)(∓)yi`

`"note that "(x+yi)(x-yi)=x^2+y^2larrcolor(blue)"a real number"`

`"the conjugate of "-2+3i" is "-2color(red)(-)3i`
