If you can help me understand this.. i basically understand the examples in my book but when it comes to problems I run into factoring problems.
Find the zeros algebraically.
#1 f(x)=2x^4-2x^2-40
Then I also have to analyze it.. in these problems..
#2 f(x)=2x^4-6x^2+1
#3 f(x)=x^5+3x^3-x+6

these have to be done with a graphing utility to approximate the zeros and then check by calculating.. another problem my graphing calculator i s not very accurate.. it is not broken not old.. it just is not very exact.. it jumps when i have it on trace mode.. from like x=0.5 to next is x= -0.8 and i am wanting to find X=0 .. the only way to get to that is to not use the trace but still then it only gives me one decimal place when i should be getting 3..
if you know how to fix that then i will be happy.. but if you don't think it is much of a problem that is ok.. but i keep on getting the wrong answer for the 3 decimal points.

1. Is this expression false? Explain why or why not.
(square root of 2) + (square root of 6) = (square root of 8)

2. Find the area of the rectangle.
Top: square root of 3 + square root of 5
Right Side: square root of 3 + square root of 5
**This is not a typo. I'm supposed to find the area of the rectangle but it seems to me like it's a square. Please help explain.
