# MPM1D Working with Polynomials 2017-10-02

We’ve learned how to multiply monomials, such as:

$3x^2(-4xy^2)=-12x^3y^2$

(page from that day: 06 – Multiplying Monomials)

$-5x(3x^2-8) = -15x^3+40x$

Today we worked on Fractice and then practised adding and subtracting polynomials, such as:

$(3x^2+4x)-(-2x^2+5)=5x^2+4x-5$

Here’s the homework for tonight: 08 – Adding and Subtracting Polynomials

Tomorrow we’ll be multiplying polynomials by other polynomials. Should be fun :)
