WEEK 5 – MATH 11 – Simplifying Binomials and Trinomials

This week we learned stuff along the lines of CDPEU and other stuff to help us simplify binomials and trinomials.

for example,

lets say I have something that looks like this,
$(X)^{2}-16=0$

this binomial would look somehing like this once it is simplyfied
$(X+n)(X-n)=0$

Now, what time what makes 16,
$4$
So it would look like this
$(X+4)(X-4)=0$

$X * X=(X)^{(2)}$
$4 * -4=-16$
$X * 4=4X$
$X * -4=-4X$

once you combine all of these you get,
$(X)^{(2)}-16=0$
