1. When the polynomial P(x) is divided by (x+1)(x-2) its remainder is 18x+17. What is the remainder when P(x) is divided by (x-2)?

Ans = 51

2. If a>0 and the function f(x) = ax^3 + bx^2 + cx + d is always increasing, what is the condition on a, b and c?

a)(b^2)-ac<0

b)(b^2)-2ac<0

c)(b^2)-3ac<0

d)(b^2)-4ac<0

For question 2, how do you go about solving it

3. What is the number of solutions of the equation ln|(x^2)-1| (Absolute value)

EDIT:

3. What is the number of solutions of the equation ln|(x^2)-1| = 0 (Absolute value) I done goofed lol
