m^2+9/m+3, no it was wrote like this in the book but i guess it could have parentheses?

[hopetrammell2004]

it's just confusing me because my problems say simplify then multiply and simplify then multiply and do not simplify

(m² + 9)/(m + 3)
= (m² + 6m + 9 - 6m)/(m + 3)
= (m² + 6m + 9)/(m + 3) - 6m/(m + 3)
= (m + 3)²/(m + 3) - 6m/(m + 3)
= (m + 3) - 6m/(m + 3)
