Q1: Given that 4x^3 - 6x^2 + 1 =(x - 2)(x + 1)Q(x) + ax + b where Q(x) is a polynomial.Find a and b.

Q2: Find the value of the unknown constants for the identities: 3x^2 + 6x - 4= p(x - q)^2 + r.
Q3: When ax^2 + bx - 6 is divided by x + 3, the remainder is 9.. Find in terms of a only...the remainder when 2x^3 - bx^2 + 2ax - 4 is divided by x - 2.

Q4: The expressions 8x^3 + ax^2 + bx - 9 leaves remainders -95 and 3 when divided by x + 2 and 2x - 3 respectively. Calculate the value of a and b.


PLZ SOLVE THEM...i WILL BE VERY THANKFUL 2 U...........................tHE FOLLOWING QUESTIONS ARE REGARDING REMAINDER AND FACTOR THEORAMS

i watched it land the other day, and it was loud, i didnt know that it was running when it came back into the atmosphere. I thought it glided back to land because it cant fly on its own? And if it does glide, what if its going to fast/slow on approach?

See the following reaction:
2FeCl3+H2S------>2FeCl2+2HCl+S

In this reaction why "FeS" not produced?

Don't you tell me one plus one equals two because one apple and one apple makes two apple.(that's what my kindergarden teacher does) When I ask you why is the sky blue you don't point me the sky and say that the sky is blue! Similarly...why makes one plus one equals to two?
