Identify your variables.
Make one of the variables equal zero and solve for the other variable.
Once you have a solution for this varaible this solution is called a zero.
Make the other variable equal to zero and solve for the other variable.
Once you have a solution for this variable this solution is also called a zero.
when the equation is equal to zero. . .:)
Yes, the places where the graph of a polynomial intercepts the x-axis are zeros. The value of y at those places must be 0 for the polynomial to intersect the x axis.
Yes.

Zeros and factors are closely related in polynomial functions. A zero of a polynomial is a value of the variable that makes the polynomial equal to zero, while a factor is a polynomial that divides another polynomial without leaving a remainder. If ( x = r ) is a zero of a polynomial ( P(x) ), then ( (x - r) ) is a factor of ( P(x) ). Thus, finding the zeros of a polynomial is equivalent to identifying its factors.
The Rational Root Theorem is useful for finding zeros of polynomial functions because it provides a systematic way to identify possible rational roots based on the coefficients of the polynomial. By listing the factors of the constant term and the leading coefficient, it allows you to generate a finite set of candidates to test. This can significantly reduce the complexity of finding actual zeros, especially for higher-degree polynomials, and assists in simplifying the polynomial through synthetic division or factoring. Ultimately, it helps streamline the process of solving polynomial equations.
A quadratic polynomial must have zeros, though they may be complex numbers.A quadratic polynomial with no real zeros is one whose discriminant b2-4ac is negative. Such a polynomial has no special name.
Try the quadratic formula. X = -b ± (sqrt(b^2-4ac)/2a)
The zeros of a polynomial represent the points at which the graph crosses (or touches) the x-axis.
Yes, a polynomial can have no rational zeros while still having real zeros. This occurs, for example, in the case of a polynomial like (x^2 - 2), which has real zeros ((\sqrt{2}) and (-\sqrt{2})) but no rational zeros. According to the Rational Root Theorem, any rational root must be a factor of the constant term, and if none exist among the possible candidates, the polynomial can still have irrational real roots.
A polynomial of degree ( n ) can have at most ( n ) distinct zeros (roots) in the complex number system, according to the Fundamental Theorem of Algebra. These zeros may be real or complex, and they can also be repeated, meaning a polynomial can have fewer than ( n ) distinct zeros if some are counted multiple times (multiplicity). For example, a polynomial of degree 3 could have 3 distinct zeros, 2 distinct zeros (one with multiplicity 2), or 1 distinct zero (with multiplicity 3).

A polynomial of degree ( n ) can have at most ( n ) real zeros. This is a consequence of the Fundamental Theorem of Algebra, which states that a polynomial of degree ( n ) has exactly ( n ) roots in the complex number system, counting multiplicities. Therefore, while all roots can be real, the maximum number of distinct real zeros a polynomial can possess is ( n ).
The factored form of a polynomial is valuable because it simplifies the process of finding its roots or zeros, making it easier to solve equations. It also provides insights into the polynomial's behavior, such as identifying multiplicities of roots and understanding its graph. Additionally, factored form can facilitate polynomial division and help in applications such as optimization and modeling in various fields.
To find the zeros of the polynomial from the given graph, identify the points where the graph intersects the x-axis. These intersection points represent the values of x for which the polynomial equals zero. If the graph crosses the x-axis at specific points, those x-values are the zeros of the polynomial. If the graph merely touches the x-axis without crossing, those points indicate repeated zeros.
