Which linear expression is a factor of the polynomial function f(x) = x3 + 2x2 − x − 2?
likoan [24]
The function
<span>f(x) = x3 + 2x2 − x − 2
is a trinomial and it is expected that it has three factors corresponding to the three roots. The possible roots could 1, -1, 2, or -2. Trying out 1
f(1) = 1 + 2 - 1 - 2 = 0
According to the remainder theorem (x - 1) is a factor. By doing synthetic division
<u>1 </u>| 1 2 -1 -2
<u>        1  3  2
</u>     1  3 2  0
f(x) = (x - 1)(x2 + 3x + 2)
which can further be factored into
f(x) = (x -1)(x +1)(x + 2)
The three factors are
x-1
x+1
x+2
which are all linear expressions</span>

What percent of 30 is 400?
makvit [3.9K]

You can always find a percent by setting up a fraction
and then doing the division.

To set up the fraction, the top number is some percent of the bottom number.

If  400  is some percent of  30,  then the fraction is

                400 / 30 .

Do the division:     400/30  =  13.333...

To turn a number into a percent, move
the decimal point two places that way  ===> .

                             13.333...  =  1,333.333 %

400  is  (1,333 and 1/3) percent of  30 .
