<PRE><B>Question 952503</B>
w for width and L for length give area A according to wL=A.


You have an expression for area and an expression for one of the dimensions, and you want to know the other dimension.


{{{x^2+x-30=b*(x+6)}}}, using b as your other unknown expression for that dimension.


Can you factorize the area expression?  Any common factor in both the left member and the right member?</PRE>
