For the Maths Freaks out there Well I'm stuck on a few questions for polynomials at the moment and it seems I'm desperate enough to turn to Basil for help =D. Well here they are people =D. Q1) In the expansion of (x+a)^^^(x+b)^^^^^, the coefficients of [i]x[/i]^^^^^^^ and [i]x[/i]^^^^^^ are 9 and 12 respectively. Find the values of [i]a[/i] and [i]b[/i] Q2) Consider the expression P(x)= x^^^+ax^^+bx+6, where a and b are constants. When P(x) is divided by (x-2)(x+1), the remainder is 4-4x, and the quotient is x+k. a) By using the division transformation, or otherwise, find the values of a and b b) Find the value of k for the values of a and b P.S. Basil does not have superscripts and does not allow alt codes so the numbers and pro-numerals w

Homework Assistance Please? (Maths) I have maths work to do and i can't do a few hard questions can anyone help me? (By the way these questions are on Quadratics) Q1) A bag contains 3 red balls and [i]w[/i] white balls. Maggie draws two balls together from the bag. The probability that they have the same colour (Australian Spelling =D) is 1/2. Bill adopts a different procedure. He draws one ball from the bag notes its colour and replaces it. He then draws a second ball from the bag and notes its colour. The probability that both balls have the same colour is now 5/8. Find all possible values of [i]w[/i]. Q2)A rhombus has half the area of a square with the same side-length, the ratio of the long to short diagonal is: (A) 2+ root3 (B) 2-root3
