Question 827459
{{{x^2+6x+9)/ ( x^2-9)}}} ..............first factor numerator and denominator completely

{{{(x^2+3x+3x+9)/ ( x^2-3^2)}}}


{{{((x^2+3x)+(3x+9))/ (( x-3)(x+3))}}}


{{{(x(x+3)+3(x+3))/ (( x-3)(x+3))}}}


{{{((x+3)(x+3))/ (( x-3)(x+3))}}}


{{{((x+3)cross((x+3)))/ (( x-3)cross((x+3)))}}}


{{{(x+3)/ ( x-3)}}}
