Define a polynomial.

Back

A polynomial is a mathematical expression consisting of variables, coefficients, and non-negative integer exponents of variables.

Front

What is the degree of the polynomial \( 4x^3 + 3x^2 - 2x + 1 \)?

Back

The degree is 3, which is the highest exponent of the variable x.

Front

What is the leading coefficient of the polynomial \( 5x^4 - 2x^3 + 3 \)?

Back

The leading coefficient is 5, which is the coefficient of the term with the highest degree.

Front

What is the difference between a monomial and a polynomial?

Back

A monomial is a polynomial with only one term, while a polynomial can have multiple terms.

Front

What is the result of \( (x + 3)(x - 3) \)?

Back
