## Lesson goal: Factor a polynomial

Previous: Simplify an algebraic expression | Home | Next: Solve equations

We've developed a function called factor that knows how to factor most polynomial-type expressions. This means figuring out, for example, that $4x^2-4x-3$ is equal to $(2x+1)(2x-3)$.

The factor function here is use a lot like the algebra function from this past lesson.
