Answer 5

If it can't be factored easily use the quadratic formula

Answer 6

i did But i ended up with -10i + 3.16 and -10i - 3.16 which Im guessing is not right and those are definetley not the final zeros

Answer 7

-10 +/- sqrt -40 all over 2

-5 +/- i sqrt (10)

-5 + i sqrt(10)
-5 - i sqrt(10)

Answer 8

Then What?

Answer 9

Is there only one 'zero' which x=2?

Answer 10

Thats it. There are no real zeros. Those last 2 lines I wrote are the zeros, but they are both imaginary

Answer 11

So I would put no real zeros? thank you so much

Answer 12

I guess so. You could include the imaginary zeros as proof
