If you evaluate your polynomial at x= - 3, the polynomial = 0. So, that means ( x + 3 ) is a factor. Either using long division, or synthetic division, you'll find out that 2x^3 - 9x^2 + 3x + 4 remains. Then if you try x = 4 on that remaining polynomial, it will = 0. Use long division or synthetic division to find out that 2x^2 - x - 1 is left over. That trinomial factors into ( 2x + 1 ) ( x - 1 ).
factored form is ( x+3 )( x - 4 )( 2x + 1 )( x - 1 )
Here, we are required to determine how far the student described in the question is from the average.
The correct answer is Choice C: |x – 78|.
According to the question; the student received a score of x%.
As such, x% may either be greater or lesser than the average score, 78%.
- <em>To determine how far the student's score is from the average, we need to take the difference between the student's score and the average score; i.e. (x - 78)</em>
- <em>This difference may however be negative: As such, there's need to take the absolute value of (x - 78) which yields |x – 78|.</em>
<em>Therefore, the expression that could be used to determine how far the student’s score is from the average is; |x – 78|</em>

Log 10 100 =2
Basically, we have to know how to solve for x in this equation:
10^x = 100
For log3 = 9 we have to solve for x in this equation:
3^x = 9
Therefore, x = 2
