Evaluate f(x)=3x*3+8x*2+5x-7 for remainder theorem

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 

                     x-(3*x^3+8*x^2+5*x-7)=0 

 4.1     Pull out like factors :

   -3x3 - 8x2 - 4x + 7  = 

  -1 • (3x3 + 8x2 + 4x - 7) 

 4.2    3x3 + 8x2 + 4x - 7  is not a perfect cube 

 4.3      Factoring:  3x3 + 8x2 + 4x - 7 

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1:  3x3 - 7 
Group 2:  8x2 + 4x 

Pull out from each group separately :

Group 1:   (3x3 - 7) • (1)
Group 2:   (2x + 1) • (4x)

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%
