Regroup terms.
\[l\imath mx->\frac{\pi (2{x}^{2}-6\pi x+4{m}^{2})}{{x}^{2}-{\pi }^{2}}\]
Regroup terms.
\[-+l\imath mx>\frac{\pi (2{x}^{2}-6\pi x+4{m}^{2})}{{x}^{2}-{\pi }^{2}}\]
Divide both sides by \(\imath \).
\[-+lmx>\frac{\frac{\pi (2{x}^{2}-6\pi x+4{m}^{2})}{{x}^{2}-{\pi }^{2}}}{\imath }\]
Simplify \(\frac{\frac{\pi (2{x}^{2}-6\pi x+4{m}^{2})}{{x}^{2}-{\pi }^{2}}}{\imath }\) to \(\frac{\pi (2{x}^{2}-6\pi x+4{m}^{2})}{\imath ({x}^{2}-{\pi }^{2})}\).
\[-+lmx>\frac{\pi (2{x}^{2}-6\pi x+4{m}^{2})}{\imath ({x}^{2}-{\pi }^{2})}\]
Divide both sides by \(m\).
\[-+lx>\frac{\frac{\pi (2{x}^{2}-6\pi x+4{m}^{2})}{\imath ({x}^{2}-{\pi }^{2})}}{m}\]
Simplify \(\frac{\frac{\pi (2{x}^{2}-6\pi x+4{m}^{2})}{\imath ({x}^{2}-{\pi }^{2})}}{m}\) to \(\frac{\pi (2{x}^{2}-6\pi x+4{m}^{2})}{\imath m({x}^{2}-{\pi }^{2})}\).
\[-+lx>\frac{\pi (2{x}^{2}-6\pi x+4{m}^{2})}{\imath m({x}^{2}-{\pi }^{2})}\]
Divide both sides by \(x\).
\[-+l>\frac{\frac{\pi (2{x}^{2}-6\pi x+4{m}^{2})}{\imath m({x}^{2}-{\pi }^{2})}}{x}\]
Simplify \(\frac{\frac{\pi (2{x}^{2}-6\pi x+4{m}^{2})}{\imath m({x}^{2}-{\pi }^{2})}}{x}\) to \(\frac{\pi (2{x}^{2}-6\pi x+4{m}^{2})}{\imath mx({x}^{2}-{\pi }^{2})}\).
\[-+l>\frac{\pi (2{x}^{2}-6\pi x+4{m}^{2})}{\imath mx({x}^{2}-{\pi }^{2})}\]
Multiply both sides by \(-1\).
\[l<-\frac{\pi (2{x}^{2}-6\pi x+4{m}^{2})}{\imath mx({x}^{2}-{\pi }^{2})}\]
l<-PI(2*x^2-6*PI*x+4*m^2)/(IM*m*x*(x^2-PI^2))
