Upon a slight rearrangement this problem gets a lot simpler to see.
x^3-x+2x^2-2=0  now factor 1st and 2nd pair of terms...
x(x^2-1)+2(x^2-1)=0
(x+2)(x^2-1)=0  now the second factor is a "difference of square" of the form:
(a^2-b^2) which always factors to (a+b)(a-b), in this case:
(x+2)(x+1)(x-1)=0
So g(x) has three real zero when x={-2, -1, 1}

Answer: 5/6 > 29/36
<u>Find Common Denominator</u>
6: 6,12,18,24,30,36
36: 36,72,106
CD=36
<u>Multiply both sides by 6</u>
5/6×6/6=30/36
<u>Compare</u>
30/36 > 29/36
<u>Therefore</u>
5/6 > 29/36
