So for the first one it is (x-3) (x+3) this is because it is a difference of squares so you square root the 9 and the minus you do both + and - in order to keep up the - 9
The zeros are:x=3 and x=-3 (this is because you change the sign in the bracket
the others should be pretty simple to do for number 2 its a complex
the third is a simple trinomial
and fourth is simple trinomial as well
