I've been struggling a little with my algebra so during the summer break I've been working through the book Algebra Demystified and it's really helping.
But I've come across a question half way through that I can't solve, I'm not sure how to tackle it, the question and answer are
Any tips or a starting point would be greatly appreciated.
Hi, Srengam. First, kudos for working through this stuff!
Typically cubics (when the highest power of x is 3) are not easy to factor. However, the one you have can be done if you group the first two terms together and , and group the second two terms and -5 together, then factoring these groupings individually.
If that's not clear, let me know and I will write up what I mean more explicitly. Good luck!
