Thanks heaps! :)

The question is: cosA + sinA = -1/2 , 0 < A < 360. I need help solving this question as I have forgotten how to apply the t formulae to solve equations.

Back again today, Im having trouble with my polynomials in general so sorry for all the questions. The polynomial f(x)= ax2+bx+c has zeros 4 and 5, and f(-1) = 60. Evaluate a,b and c.

If anyone would be able to help me with my second question It would be appreciated, thankyou.

Re: [UrgentI have a polynomial, and I need to find a and b but don't know how! Okay thankyou, your help is much appreciated.

Re: [UrgentI have a polynomial, and I need to find a and b but don't know how! When you say "equate that to 4" what do you mean by that?

Re: [UrgentI have a polynomial, and I need to find a and b but don't know how! Thankyou so much, I have my prelim exam on Tuesday and this really helps.

This is the question and I dont know how to do it, any feedback would be appreciated. When the polynomial 2x3+ax2+bx+1 is divided by x-1 the remainder is 4; when divided by x-2, the remainder is 21. Find the values of a and b. [Edit] I also have a second question which is similar, but...
