You need to take the square root of -3 and 9. To take the square root of a negative number- we must use i which is equal to -1.

Answer 16

Oh sorry...I mean -9 and 16

bc. there is -9 and sqrt(-1)=i so from this result that havnt real roots without ,,i"

Answer 19

ok

Answer 20

so how do we get the real roots?
