Class: HL 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! __________________ follow me on ▲ instagram: shannus
