Math 10 Week 8

 

This week we started our introduction and review to polynomials. We reviewed drawing out diagrams that show multiplying polynomials. 

x^2 is shown as a square

x is shown as a stick

1 is shown as a tiny cube

ex. (2x+3)(3x-2)

I drew a right angle. On one side, I drew 2x+3 and on the other side, I drew 3x-2. I then multiplied each value.

In the picture above, I show how zero pairs (1 negetive and 1 positive) cancel eachother out.

When this happens, It value of the negetive and positive is 0. 1-1=0

to come up with the answer of 6^2 +5x-6
