0.04
Its just 30x60=1800...right?
Answer:
9/20 = 0.45
3/10 = 0.3
7/12 = 0.5833333
4/5 = 0.8
2/3 = 0.66667
5/6 = 1.6667
1/6 = 0.16667
15/16 = 0.9375
2/15 = 0.13333
4/11 = 0.3636
5/8 = 0.625
13 / 16 = 0.8125
3/25 = 0.12
4/9 = 0.4444
8/9 = 0.88889
11/16 = 0.6895
14 / 25 = 0.56
11/15 = 0.7333

<span>since the coefficients add to 0 we know that one root is x = 1 , do synthetic division ; </span>
<span>(x - 1 ) ( 2 x^3 - 5 x² - x + 6 )...now it is easy to see that x = - 1 is a root; </span>
<span>again synthetic division yields ( x - 1 ) ( x + 1 ) [ 2 x² - 7 x + 6 ]]....so </span>
<span>the smallest upper bound is x = 2 { poly = 0 at x = 2 }.. </span>
<span>thus both 4 & 5 are upper bounds </span>
<span>and since you only ask to find an upper bound then x = 1000 is certainly an answer ; </span>
<span>finally if you write the polynomial as " x [ x ( x {2x - 7 } + 4 ) + 7 ] - 6 " </span>
you can see that x = 3 is an upper bound
