Question 242008: Hi
I submitted these problems but no one has help me, can someone please help me I been out of school for 15 years and I am talking college algebra, here are the problems.

1. factor into product of 2 binomials:
5x(6x-5) -2(6x-5)
This is what I got
5*x(6*x-5) – 12*x+10

2. factor completely, if the polynomial is a prime, state this:
49y^2-49w^2
This is what I got for the answer:
49*y^-49*w^2

Note that 6x+-+5 is a factor in both terms
5x%2A%286x+-+5%29-+2%2A%286x+-+5%29
%286x+-+5%29%2A%285x+-+2%29 answer
----------------------
49y%5E2+-+49w%5E2
%287y+%2B+7w%29%2A%287y+-+7w%29
And I can factor out the 7's
7%2A%28y+%2B+w%29%2A7%2A%28y+-+w%29
49%2A%28y+%2B+w%29%2A%28y+-+w%29 answer
