What does the question you are trying to answer ask?

anonymous · Answer

Im supposed to find the polynomial function of 1, -2, and 5. i got to P(x) = (x - 1)(x + 2)(x - 5) but im not sure if there is more to it. I dont quite understand what i need to do and the person helping me went offline so im stuck.

Well if you are trying to find the polynomial function that usually entails having all the functions foiled into one equation of Ax^3 + Bx^2 + Cx + D. With A, B, C, and D as constants. Do you know how to do that?

anonymous · Answer

not really. i just learned this but being online schooled i dont understand it well

anonymous · Answer

do you mean to just simplify/distribute ?

anonymous · Answer

Okay, so we can start just for now to ignoring the (x-5). We need to do 4 multiplications to find out the answer to (x - 1) * (x + 2)
|dw:1375310450272:dw|
Then add the 1st + 2nd + 3rd + 4th and then we can multiply the (x-5) back in afterwards.
