document.write( "Question 65657: i am currently working on the carnegie learning disc. i have submitted parts of the problem twice and both times it tells me the answers were wrong, so here is the whole scenario:i have to completely simplify this rational expression but only one step at a time- this is what i came up with: (x-2)^2(x+7)/((x-2)(x+7)^2(x-8))...first step...simplify fractions,which = X-2/((x+7)(x-8)), second step: distribute in (x+7)(x-8),which= x-2/((x-8)*x+(x-8)*7...third step: factor,which equals x-2/((x-8)(x+7)). 4th step: distribute in (x-8)(x+7),which = x-2/x(x+7)-8(x+7). 5 th step: factor...which =x-2/((x+7)(x-8)).6th step: distribute in x-2/((x+7)(x-8)),which = x/((x+7)(x-8))(-2/((x+7))(x-8)). 7th step:simplify signs, which= x/((x+7)(x-8))-2/(x+7)(x-8)...then it keeps telling me to factor , but when i choose factor common factor, it wont let me do it. please check my steps and make sure i am doing them right. i have been stuck on this problem for 3 days. thanks so very much!! \n" ); document.write( "
