Front

What is the factored form of a quadratic equation?

Back

The factored form of a quadratic equation is expressed as: y = a(x - r1)(x - r2), where r1 and r2 are the roots.

Front

What is the definition of a quadratic function?

Back

A quadratic function is a polynomial function of degree 2, typically written in the form f(x) = ax² + bx + c.

Front

How do you find the vertex of a quadratic function in standard form?

Back

The vertex (h, k) can be found using the formula h = -b/(2a) and k = f(h).

Front

What is the difference between a monomial and a binomial?

Back

A monomial is an algebraic expression with one term, while a binomial has two terms.
