so use your calculator to find the zeros (when the graph crosses the x axis).

rob1525 · Answer

or use the quadratic formula but the question is asking for aproximates

anonymous · Answer

that is y i came to openstudy 
so they can help solve it

rob1525 · Answer

do you have a graphing calculator?

anonymous · Answer

no

rob1525 · Answer

u need one to do this problem.

anonymous · Answer

well i dont have one

anonymous · Answer

the above expression can be factorized as (x-2.63)(x+2.04)
thus x=2.64 and x=-2.04 is the right answer
