اذا كان f left parenthesis x right parenthesis equals fraction numerator x over denominator 3 x minus 1 end fraction


و h left parenthesis x right parenthesis equals fraction numerator 4 x squared plus 1 over denominator x minus 1 end fraction


فإن f left parenthesis x right parenthesis minus left parenthesis h x right parenthesis يساوي:


fraction numerator negative 12 x cubed minus 5 x squared minus 4 x plus 1 over denominator 3 x squared minus 4 x minus 1 end fraction


fraction numerator negative 12 x cubed space plus space 5 x squared space minus space 4 x minus 1 over denominator 3 x squared plus 4 x plus 1 end fraction


fraction numerator negative 12 x cubed space plus space 5 x squared minus 4 x plus 1 over denominator 3 x squared minus 4 x plus 1 end fraction


fraction numerator negative 12 x cubed minus 5 x squared plus 4 x plus 1 over denominator negative 3 x squared minus 4 x plus 1 end fraction
