To find the real zeros of a polynomial, you need to input the coefficients of the polynomial into the calculator. The real zeros are the values of x that make the polynomial equal to zero.

For example, if you have a polynomial like x² – 3x + 2, the coefficients would be 1, -3, 2. The real zeros of this polynomial can be found using various methods such as factoring, using the quadratic formula, or numerical methods.

Real zeros are important in various fields such as engineering, physics, and economics, as they can represent critical points in a function, such as maximum or minimum values, or points of intersection with the x-axis.

Understanding Real Zeros

Real zeros of a polynomial are the x-values where the polynomial evaluates to zero. These points are crucial for graphing the polynomial and understanding its behavior. The number of real zeros can vary based on the degree of the polynomial and its coefficients.

For a quadratic polynomial (degree 2), there can be two, one, or no real zeros depending on the discriminant (b² – 4ac). If the discriminant is positive, there are two distinct real zeros; if it is zero, there is one real zero (a repeated root); and if it is negative, there are no real zeros.
