Front

What are zeros of a polynomial?

Back

Zeros of a polynomial are the values of x for which the polynomial equals zero. They are also known as roots.

Front

How do you determine the distance between zeros of a polynomial?

Back

To find the distance between zeros, calculate the absolute difference between the zeros. For example, if the zeros are x1 and x2, the distance is |x1 - x2|.

Front

What does it mean for a function to be negative on an interval?

Back

A function is negative on an interval if its output values (y-values) are less than zero for all x-values in that interval.

Front

What is the significance of complex zeros in polynomial functions?

Back

Complex zeros occur in conjugate pairs and indicate that the polynomial does not cross the x-axis at those points. For example, if a polynomial has a zero of 4+i, it also has a zero of 4-i.

How do you find the area of a shaded region in a geometric figure?

Back

To find the area of a shaded region, subtract the area of the unshaded part from the total area of the figure.

Front

What is the relationship between the degree of a polynomial and the number of zeros?

Back

The degree of a polynomial indicates the maximum number of zeros it can have. For example, a cubic polynomial (degree 3) can have up to 3 zeros.

What is the formula for the area of a rectangle?

Back

The area A of a rectangle is given by the formula A = length × width.
