\\ \sf\longmapsto f(x)=4x^2-5x


\\ \sf\longmapsto g(x)=3x^2+6x-4

Now


\\ \sf\longmapsto (f-g)(x)


\\ \sf\longmapsto f(x)-g(x)


\\ \sf\longmapsto 4x^2-5x-(3x^2+6x-4)


\\ \sf\longmapsto 4x^2-5x-3x^2-6x+4


\\ \sf\longmapsto x^2-11x+4

very easy


\displaystyle\ (f-g)(x)=f(x)-g(x)=4x^2-5x-3x^2-6x+4=\boxed{x^2-11x+4}
