What is a polynomial?

Back

A polynomial is a mathematical expression consisting of variables (also called indeterminates) raised to whole number powers and coefficients. For example, 5x^2 - 13x + 6 is a polynomial.

What does it mean to factor a polynomial?

Back

Factoring a polynomial means expressing it as a product of its factors. For example, the polynomial 5x^2 - 13x + 6 can be factored into (5x - 3)(x - 2).

How do you solve a radical equation?

Back

To solve a radical equation, isolate the radical on one side of the equation and then square both sides to eliminate the radical. Check for extraneous solutions afterward.

What is the degree of a polynomial?

Back

The degree of a polynomial is the highest power of the variable in the polynomial. For example, in the polynomial 4x^3 + 2x^2 - x, the degree is 3.

What is long division of polynomials?

Back

Long division of polynomials is a method used to divide a polynomial by another polynomial, similar to long division with numbers. It involves dividing, multiplying, and subtracting.

What is the remainder theorem?

Back

The remainder theorem states that if a polynomial f(x) is divided by (x - c), the remainder of that division is f(c).

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. For example, 3x is a monomial, while 3x + 2 is a polynomial.

What is the zero product property?

Back

The zero product property states that if the product of two factors is zero, then at least one of the factors must be zero. For example, if (x - 3)(x + 2) = 0, then x = 3 or x = -2.

How do you factor the expression x^2 + 7x - 30?

Back

To factor x^2 + 7x - 30, look for two numbers that multiply to -30 and add to 7. The factors are (x + 10)(x - 3).
