Question 644044
{{{9/(x+7) + (x+9)/(x^2-49) + 9/(x-7)}}}


{{{9/(x+7) + (x+9)/(x^2-7^2) + 9/(x-7)}}}


{{{9/(x+7) + (x+9)/((x-7)(x+7)) + 9/(x-7)}}}



{{{(9(x-7) + (x+9) + 9(x+7))/((x-7)(x+7))}}}


{{{(9x-63 + x+9 + 9x+63)/((x-7)(x+7))}}}


{{{(19x-cross(63) +9 +cross(63))/((x-7)(x+7))}}}


{{{(19x+9 )/((x-7)(x+7))}}}
