Why are polynomials equated to zero?

Equal to zero means there is no other equation of “x” for the calculation. You equate a polynomial to zero only when you are asked to find out zeros or roots of the polynomial. A zero or root of the polynomial is that value of x, which when you substitute it in the polynomial, you get the answer as zero.

What is a zero for a polynomial function?

The zeros of a polynomial p(x) are all the x-values that make the polynomial equal to zero. They are interesting to us for many reasons, one of which is that they tell us about the x-intercepts of the polynomial’s graph. We will also see that they are directly related to the factors of the polynomial.

Is it necessary for a zero to zero a polynomial?

Explanation: Zero polynomial is a constant polynomial whose coefficients are all equal to 0. Zero of a polynomial is the value of the variable that makes the polynomial equal to zero. Therefore, zero of the zero polynomial is any real number.

Are zero polynomials and zero polynomials the same?

A Zero Polynomial is a polynomial in which all variable coefficients are all equal to zero. It is a constant polynomial with value 0. Zeros of the polynomial is the value of x which makes the entire equation or polynomial equal to 0.

Does a polynomial have to equal zero?

No. Zero is not a polynomial. By definition, Polynomial is an expression that can have constants, variables and exponents, that can be combined using addition, subtraction, multiplication and division, but: no division by a variable.

Are polynomials equal to zero?

Asking you to find the zeroes of a polynomial function, y equals (polynomial), means the same thing as asking you to find the solutions to a polynomial equation, (polynomial) equals (zero). The zeroes of a polynomial are the values of x that make the polynomial equal to zero.

Why do you think that a in quadratic equation should not be equal to 0?

If a=0 , the denominator of the formula is zero, which results in an undefined quantity. Conceptually, this makes sense because if a=0 , then the function f(x)=ax2+bx+c f ( x ) = a x 2 + b x + c is not quadratic, but linear!

Do polynomials always equal 0?

A polynomial function may have zero, one, or many zeros. All polynomial functions of positive, odd order have at least one zero, while polynomial functions of positive, even order may not have a zero. Regardless of odd or even, any polynomial of positive order can have a maximum number of zeros equal to its order.
