ThanksAnswered by Penny Nom.     Simplify the expression 2012-02-12 From Christy:Hi guys, ok so I'm having problems with solving this equation since it's been so long I've done precal. I have to find critical points so I have to find the derivative first. This is what I've done so far s(t)= (t-6)^4 * (t+1)^2 t'= 4(t-6)^3*(1)*(t+1)^2+ 2(t+1)(1)*(t-6)^4 so this is where I got stuck, which is the algebra part. How can I simplify this to get the answer to figure out the critical points.Answered by Penny Nom.     An algebraic exercise with fractions and radicals 2008-11-18 From Rubén:Question from Rubén, a teacher: I have the ecuation: U = [yb / (ab+a^2)]^1/2 + [ya / (ab+b^2)]^1/2 I know for sure this reduces to U = [y (1/a + 1/b)]^1/2 but I cannot find a way to get into that result! ThanksAnswered by Rubén Osuna.
