okay what is the question?

anonymous · Answer

the question is
Your friend runs up to you, scared that he is not ready for the upcoming quadratics test. To help him study, you will create four different quadratic functions. Then demonstrate to him how to rewrite each function as a group of factors, if possible.
The function f(x) is a difference of squares.
The function g(x) is a sum of squares.
The function h(x) is a perfect square trinomial.
The function j(x) can only have a GCF factored out of it.

anonymous · Answer

its okay

agent0smith · Answer

The function f(x) is a difference of squares.... eg$$\Large  f(x) = x^2 - 4$$

agent0smith · Answer

Can you factor it?

anonymous · Answer

I think so...

agent0smith · Answer

Use this$$\Large a^2 - b^2 = (a+b)(a-b)$$

anonymous · Answer

yes so it would be $$(x+2) (x-2)$$

agent0smith · Answer

Correct. Now try the next one:

The function g(x) is a sum of squares.

a sum of squares is the same thing as a diff of squares, but with a plus sign not a minus sign between the two terms
