An equilateral triangle ABC has AB=20√3. P is a point placed in triangle ABC and D,E and F are the foot of the perpendiculars from P to AB, BC and AC, respectively. If PD=9 and PE=10, what is the value of the length of PF? Please work the complete solutio...

Suppose f(x) is a polynomial of degree of 5 and with leading coefficient 2009. Supposdm further that f(1) = 1, f(2) = 3, f(3) = 5, f(4) = 7, f(5) = 9. What is the value of f(6). The answer given in book is 241091. Please work the complete solution.

Let p and q be the roots of the polynomial mx^2 + x(2 - m) + 3. Let m1 and m2 be two values of m satisfying p/q + q/p = 2/3. Determine numerical value of m1/(m2)^2 + m2/(m1)^2. Please work the complete solution.

Why didn't you guys are answering my questions at all. 8 question posted tomorrow but not even a single question is answered yet.

Please explain it a bit furthur. Why did you took g(x) = f(x) - 2x + 1.
