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.

Move the mouse over a dotted box for more information.

Now you try. Try factoring just about any expression you can find in your algebra book, and see what you get.

Type your code here:

See your results here:

This example will factor $4x^2-4x-3$. You might also try factoring:
  • $9x^2+21$
  • $t^3-3t^2+t-3$
  • $u^2+u-56$
  • $12x^2-5x-2$
  • $10b^2-38b+24$
