geeknick Posted November 9, 2011 Share Posted November 9, 2011 getting lots of stuck from this algebraic expression ?? 1. The problem statement, all variables and given/known data (4x−1)1/2−1/3(4x−1)3/2 2. Relevant equations 3. The attempt at a solution I think the GCF is (4x−1)1/2 . So, I get (4x−1)1/2(1+(−1/3(4x−1))) = (4x−1)1/2(−4/3x+4/3) = −4/3(4x−1)1/2(x−1) However, the answer in the book is 4/3(4x−1)1/2(x−1) . I've done it several ways, and I either get a minus sign on the 4/3 , or the (x−1) becomes (x+1) . What am I missing? Link to comment Share on other sites More sharing options...
