Answer:
1/4 page per minute
Step-by-step explanation:
To find the unit rate, we need the amount of page she read in 1 minutes. To do this we divide the pages by the minutes. Let x equal the pages she reads per minutes.
5/20=x
we can simplify the fraction by divide both the numerator and denominator by 5
(5/5)/(20/5)=x
Do the division
1/4=x
Olive reads 1/4 page per minute
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}
You can take out an x
X(6x^2+5x-4)
Then factor it
X(3x+4)(2x-1)
Answer: All real numbers less than or equal to 3.
