Lesson goal: Polynomials multiplied by a monomial
Previous: Introduction: combining exponents
| Next: Raising polynomials to some power
In the last lesson
, you saw how the
function knows how to crunch algebraic
symbols (x, y, z, etc.) for you, in figuring out exponents.
Let's use this more now to multiply a polynomial by a monomial, and practice the distributive property of multiplication.
This means doing problems like $-x(x^2-4)$ or $-5u(u^2+4)$.
Now you try. Try some problems out of your math book!
Type your code here:
This will find the answer to $(x+2)^2$.
You can try all kinds of expression with this (ones you wouldn't dare do by hand), like:
