1) x³ + 2x² - x - 2 2) 2x³ + 5x² - 8x - 20 = 0

x²(x + 2) - (x + 2) x²(2x + 5) - 4(2x + 5) = 0

(x + 2)(x² - 1) (2x + 5)(x² - 4) = 0

(x + 2)(x - 1)(x + 1) x = -5/2, +-2

x = -2, 1, -1 << a is the answer.

hope that helps, God bless!

Answer:

<h2>The correct answer for this question is 78.</h2>

Step-by-step explanation:

The average or mean of any variable or mathematical phenomenon is calculated as the division of the sum of all the numbers or items within the particular variable by the total number of items or numbers within the variable.
In this case, the marks of the 4 exams in the semester are 77,90,85 and 100 respectively.There are total 5 exams in the semester.
Let's suppose that the marks for the 5th exam is x.
Therefore, based on the mathematical formula to compute average or mean,to get an overall average of 86 including all the 5 exams, one has to get:-

$\frac{77+90+85+100+x}{5}=86$
