So you have the expression "c²x² + x² - c² - 1". What are you supposed to do with this. (No instructions were included within your message.)

Please reply, showing how far you have gotten.

P.S. Please post any further algebra questions to one of the "algebra" categories. Thank you.

Hello, stargil2989!

Factor: C²x² + x² - C² - 1
.

When given four or more terms, think of factoring "by grouping".

Factor: .x²(C² + 1) - (C² + 1)

Factor: .(C² + 1) (x² - 1)

Factor: .(C² + 1) (x - 1) (x + 1)
