what is a cubic polynomial function in standard form with zeros 1,-2, and 2? f(x)=x³-x²-4x+4 Which points are the best approximations of the relative maximum and minimum of the function? f(x)=x³+6x²-36x A quadratic equation is one of the form ax 2 + bx + c = 0, where a, b, and c are numbers, and a is not equal to 0. Factoring. This approach to solving equations is based on the fact that if the product of two quantities is zero, then at least one of the quantities must be zero. In other words, if a*b = 0, then either a = 0, or b = 0, or both.
Standard Forms The standard form of a polynomial is f(x) = a n x n + a n-1 x n-1 + . . . + a 1 x + a 0. The a i are real numbers and are called coefficients. The term a n is assumed to be non-zero and is called the leading term. The degree of the polynomial is the largest exponent of x which appears in the polynomial -- it is also the subscript ...

A negative semi-definite quadratic form is bounded above by the plane x = 0 but will touch the plane at more than the single point (0,0). It will touch the plane along a line. Figure 4 shows a negative-definite quadratic form. An indefinite quadratic form will notlie completely above or below the plane but will lie above

Notice that we start with the factored form, which obviously has three zeros (one at x = 1, one at x = 2, and one at x = 3), and then use distributivity of multiplication to find the polynomial expression. Let's take a look at the graph of this function to confirm the location of the zeros.
Finding the zeros of a polynomial function (recall that a zero of a function f(x) is the solution to the equation f(x) = 0) can be significantly more complex than finding the zeros of a linear function. For simplicity, we will focus primarily on second-degree polynomials, which are also called quadratic functions.

The degree of a polynomial is given by the term with the greatest degree. A polynomial with one variable is in standard form when its terms are written in descending order by degree. So, in standard form, the degree of the first term indicates the degree of the polynomial, and the leading coefficient is the coefficient of the first term.
