Question 189554
I'm assuming that the equation is {{{ax+bx=a^2+2ab+b^2}}} and that you want to solve for "x"



{{{ax+bx=a^2+2ab+b^2}}} Start with the given equation.



{{{x(a+b)=a^2+2ab+b^2}}} Factor out the GCF "x"



{{{x=(a^2+2ab+b^2)/(a+b)}}} Divide both sides by {{{a+b}}} to isolate "x".



{{{x=((a+b)(a+b))/(a+b)}}} Factor



{{{x=(highlight((a+b))(a+b))/highlight(a+b)}}} Highlight the common terms. 



{{{x=(cross((a+b))(a+b))/cross(a+b)}}} Cancel out the common terms. 



{{{x=a+b}}} Simplify



So the solution is {{{x=a+b}}} where {{{a<>-b}}}
