Question 443227

{{{(x^2 - 3x + 2)/(x^2 + 8x - 9)}}}....replace {{{- 3x}}} with {{{- x-2x}}}, and  {{{8x}}} with {{{- x+9x}}}

{{{(x^2 - x -2x + 2)/(x^2 -x+9x - 9)}}}.....group


{{{((x^2 - x) -(2x - 2))/((x^2 -x)+(9x - 9))}}}


{{{(x(x - 1) -2(x - 1))/(x(x -1)+9(x - 1))}}}


{{{((x -2)(x - 1))/((x+9)(x - 1))}}}


{{{((x -2)cross((x - 1)))/((x+9)cross((x - 1)))}}}


{{{(x -2)/(x+9)}}}
