Solution

Problem 5 :

When 3x² + x + 2 is divided by x - 1, the result can be expresses as

(ax + b) + c/(x - 1)

where a, b and c are constants. What is the value of a + b + c?

Solution

Problem 6 :

When 2x² - 5x + 3 is divided by 2x + 1, the result can be written as (x - 3) + R / (2x + 1), where R is a constant. What is the value of R?

Solution

Problem 7:
