Question

Which of the following strategies is appropriate for factoring polynomials with 2 terms?
A.
determine if the polynomial is the sum of two squares
B.
determine if the polynomial is the difference of two squares
C.
determine if the polynomial is a perfect square trinomial
D.
determine if it can be factored by grouping

Answer 1

Each would work...

A would work if the two terms were x^2 and 25
-> x^2 +25
(This is not possible, it cannot be A)

B would work if the two terms were x^2 and 25
-> x^2 - 25

C would work if you had 3 terms, but you only have 2 so forget C.

And D, you need 4 terms. So forget D.

Answer 2

Thanks so much :)
