what would i do with questions like

a)4n^2-49

b)n^2+8n+12

c)2a^2+11a+30

[mathwithmrv]

@DoubleEmzeez The first one is "difference of perfect squares". Search my video channel for several videos I have showing those examples. The other 2 can be done with the factor box method, also on my video channel. I think those will help. Let me know if I should make something specific to help you out, OK? Thanks for watching, Terry V

what if the problem is 16x^2-1

^2 means its squared

@gabbyf22 Hi, Gabby, thanks for watching. Your question relates to some special cases of factoring. I have some videos about those. Look for "How to Factor Polynomials: Problem Set 5" and #6.

To answer your question, 16x^2 -1 would be factored like this:

(4x + 1) (4x - 1) This is known as factoring a "Difference of 2 Perfect Squares". Terry V

oh my god, u just saved my life! thanks!

These are easy to factor.. I have problems with problems like these. 1) 4x^4-9.. 2) (y+1)^2-36. 3) 27y^3-8 4) (a-3)^3+64 5) 9a^4+24a^2+b^2+16b^4

6) 4x^4-24x+36 7) 9x^2+54x+C 8) (y-3)^2+8(y-3)+16 9)2x^4+24x^2y^2+72y^4 10)27x^2y-48y 11)16x^4-y^4 12) 25-(y^2+6y+9)  If you have problems like these. Let me know.. These are the ones I need help on.. I'm sure there are certain formulas to follow too and that is why it's confusing.
