Find the real zeros of f(x)=x3+2x2−5x−6. Finding Zeros: In this problem, we want to find the real zeros of a cubic polynomial. Whenever this is the case, the first thing we want to do is try simple solutions by investigation. Some of the first values to con...
Thus zero of the cubic polynomial becomes the root of the cubic equation. Unlike a quadratic equation which has the quadratic formula to find its roots, the cubic equation has no simple formula to find its roots. Thus we proceed by using the rational root theorem to find one of its roots...
Since p(3)=0, p(−2)=0, and p(1)=0, we have verified that 3,−2,1 are indeed the zeros of the polynomial p(x). Step 4: Verify the Relation Between Zeros and CoefficientsFor a cubic polynomial of the form p(x)=ax3+bx2+cx+d, the relations between the zeros α,β,γ ...

In this paper, we derive the explicit formulas for computing the zeros of certain cubic quaternionic polynomial. From these, we obtain a necessary and sufficient condition to quaternionic cubic polynomial have a spherical zero, and some examples are also provided. Moreover, we will discuss some ...
This problem can be solved by writing a cubic function and solving a cubic equation for the volume of the cake. In this section, we will discuss a variety of tools for writing polynomial functions and solving polynomial equations.Evaluate a polynomial using the Remainder Theorem...
Combining a suitable two-point iterative method for solving nonlinear equations and Weierstrass' correction, a new iterative method for simultaneous finding all zeros of a polynomial is derived. It is proved that the proposed method possesses a cubic convergence locally. Numerical examples demonstrate a...
We say that x=hx=h is a zero of multiplicity p. The graph of a polynomial function will touch the x-axis at zeros with even multiplicities. The graph will cross the x-axis at zeros with odd multiplicities. The sum of the multiplicities is the degree of the polynomial function....
Enter the given function in the expression tab of the Zeros Calculator to find the zeros of the function. This is a polynomial function of degree 4. Therefore, it has four roots. All the roots lie in the complex plane. The roots of the function are given as: ...
