Find the two products below. Compare and contrast, in complete sentences, the similarities and differences of the two. (x + 6)(x − 6) and (x − 6)(x − 6)
the first one is difference of two squares. the second is square of a binomial
can you compare?
First FOIL the 1st and 2nd one.
what is foil?
Because the 1st one is a difference of squares, the middle term will cancel out and it will be a 2 term polynomial. And the 36 at the end will be negative. Where as the other is the opposite and will have 3 terms and the middle term wont cancel out. The 36 at the end will be positive. Both deal with 6's and x^2s.
It's first outter inner last. When you combine 2 binomials.
oh alright thank you :)
Yw. But you still need to FOIL to get your 2 products.
so how do I do that?
