1. You have to find P(2), assuming you know your remainder theorem.
Sub x = 2 to get your answer
2. You have to see that f'(x) >0 and therefore you use the discriminate on f'(x) and make that negative.
3. That's not even an equation
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

Yikes, my bad, fixed it, Q3 should of been equal to 0
For question 2, i derived it but not sure how to get an answer out of it
Thx
