Find the value of c so that (x+2) is a factor of the polynomial p(x). p(x)=4x^3+cx^2+x+2
Wittaler [7]

Answer:

c = 8

Step-by-step explanation:

Use synthetic division here; it's the fastest approach.

Given that (x + 2) is a factor, take -2 and use this as the divisor in synthetic division:

-2     4         c                1           2

                  -8    (-2c+ 16)      (4c-34)

       ---------------------------------------------

         4    (c - 8)   (-2c + 17)     4c - 32

The remainder, 4c - 32, must equal zero if (x + 2) is a factor.

Then 4c - 32 = 0, and c = 8

The mayor of a town receives 75% of the votes in a town election. If 680 people voted, how many votes did the mayor receive? 360
7nadin3 [17]
First you need to put everything as 1 unit. I'll convert both to fractions for now.
75% = 3/4

680/1 * 3/4

Cross Multiply

2040/4

Simplify

510

The mayor received 510 votes.
