Question Number 96007 by 6532 last updated on 29/May/20
((9x^2 +4a^2 )/(9x^2 −4a^2 )) +((3x)/(3x+2a)) −((2a)/(2a−3x))
$$\frac{\mathrm{9x}^{\mathrm{2}} +\mathrm{4a}^{\mathrm{2}} }{\mathrm{9x}^{\mathrm{2}} −\mathrm{4a}^{\mathrm{2}} }\:+\frac{\mathrm{3x}}{\mathrm{3x}+\mathrm{2a}}\:−\frac{\mathrm{2a}}{\mathrm{2a}−\mathrm{3x}} \\ $$

((9x^2 +4a^2 )/(9x^2 −4a^2 )) + ((3x)/(3x+2a))+ ((2a)/(3x−2a)) =   ((9x^2 +4a^2 +9x^2 −6ax+6ax+4a^2 )/(9x^2 −4a^2 )) =  ((18x^2 +8a^2 )/(9x^2 −4a^2 ))
$$\frac{\mathrm{9}{x}^{\mathrm{2}} +\mathrm{4}{a}^{\mathrm{2}} }{\mathrm{9}{x}^{\mathrm{2}} −\mathrm{4}{a}^{\mathrm{2}} }\:+\:\frac{\mathrm{3}{x}}{\mathrm{3}{x}+\mathrm{2}{a}}+\:\frac{\mathrm{2}{a}}{\mathrm{3}{x}−\mathrm{2}{a}}\:=\: \\ $$$$\frac{\mathrm{9}{x}^{\mathrm{2}} +\mathrm{4}{a}^{\mathrm{2}} +\mathrm{9}{x}^{\mathrm{2}} −\mathrm{6}{ax}+\mathrm{6}{ax}+\mathrm{4}{a}^{\mathrm{2}} }{\mathrm{9}{x}^{\mathrm{2}} −\mathrm{4}{a}^{\mathrm{2}} }\:= \\ $$$$\frac{\mathrm{18}{x}^{\mathrm{2}} +\mathrm{8}{a}^{\mathrm{2}} }{\mathrm{9}{x}^{\mathrm{2}} −\mathrm{4}{a}^{\mathrm{2}} }\: \\ $$
