Multiple representations

We’ve been working on factoring trinomials and multiplying binomials a lot this past week in grade 10.  We can do it with the distributive property, and decomposition and with algebra tiles.

Some of the expressions we get are pretty neat.  This one will simplify to 4x^2-9.

The next representation we’re connecting is the graphical.  We looked at some equations in desmos today to notice some things about them.  X and y intercepts were some good hangs to consider.
