One of these intercepts is a stationary point if inflection.
Y ax 4 bx 3 cx 2 dx e. A quartic function has a equation y ax 4 bx 3 cx 2 dx e. Hàm số đồng biến trên khoảng b. If so the polynom can be factorized as follows it is a bit complicated though.
Let us then examine x4 x2 k1 x k2 0 eq1. Ax 4 bx 3 cx 2 dx e 0 with a 0 this gets messy quite quickly so i will just give a sketch of one method.

Previous question next question transcribed image text from this question. For math a neq 0 math if this equation admits four different roots checkable by plotting the function a tool like desmos can do the job. Cho hàm số y f x ax4 bx3 cx2 dx e đồ thị hình bên là đồ thị của hàm số y f x.
Multiply by 256a 3 and substitute t 4ax b to get a depressed monic quartic of the form. This problem has been solved. It is symmetrical about the y axis at 2 18 gradient 0 y 0 x 1 show that b d 0 find the values of a c e with working thx.
According to évariste galois wikipedia and niels henrik abel wikipedia who independently in the early 1800 found this result there is no general formula for algebraic equations of degree more or equal to 5. For equations of third degree gero. Where i sqrt 1 therefore x2 z1 21 2i z1z2 1 4 z1 22 eq3.
