3rd degree polynomial (math)
I don't know whether it's a good idea asking you guys, since I probably don't know the right translations for the following math problem:
(am really a math noob, so idk what to do)
A 3rd degree polynomial has the same zeroing as function g(x)=x²-x-2.
It subtends the y - axis (ordinate) with P(0|2) and has the slope of -3.
What's the equation of the 3rd degree polynomial?
So far I know that the "base frame" for the polynomial is:
f(x)= ax³+ bx² + cx +d
and the first derivation is
f′(x)= 3ax² + 2bx +c
Also the zeroings of g(x) are Z1(-1|0) and Z2(2|0)
Idk what to do next cos i dont really understand a thing and what I just did there lol.
Also dunno whether you guys understand me (me and my translator lol).
But I would appreciate any helps!
