Do you know how to use synthetic division?

anonymous · Answer

no

anonymous · Answer

lol. to make things easier for you, check out my profile, since I just answered a question similar to yours. I had to use synthetic division to find all the zeroes, which is what you need

anonymous · Answer

did you check it out?

anonymous · Answer

well did you?

anonymous · Answer

it's a pretty long division

anonymous · Answer

well here it is

anonymous · Answer

you still have to keep going with  $$x ^{2}+x-5$$

anonymous · Answer

use  the quadratic  formula to get the remaining zeroes.

anonymous · Answer

I already found 3 for you, but you need find the remaining two

anonymous · Answer

I'm sorry I made a mistake: at the end you are left with $$2x ^{2}-5$$

anonymous · Answer

solve for x and you get  x= +- 1.58113883
