Question 175059
can you please help me {{{cross(solve)}}}simplify: 

{{{matrix(1,3,
(x^2-9)/(x+2),  "×", (x^2-4)/(x^2-9) )}}}

<pre><font size = 4  color = "indigo"><b>

Factor the left numerator and the right numerator
and denominator:
{{{matrix(1,3,
((x-3)(x+3))/(x+2),  "×", ((x-2)(x+2))/((x-3)(x+3)) )}}}


Put parentheses around the left denominator:

{{{matrix(1,3,
((x-3)(x+3))/((x+2)),  "×", ((x-2)(x+2))/((x-3)(x+3)) )}}}

Indicate the multiplication of the numerators and denominators
all as one fraction:

{{{matrix(1,1,
((x-3)(x+3)(x-2)(x+2))/((x+2)(x-3)(x+3)))}}}

Cancel the {{{(x-3)}}}'s

{{{matrix(1,1,
((cross(x-3))(x+3)(x-2)(x+2))/((x+2)(cross(x-3))(x+3)))}}}

Cancel the {{{(x+3)}}}'s

{{{matrix(1,1,
((cross(x-3))(cross(x+3))(x-2)(x+2))/((x+2)(cross(x-3))(cross(x+3))))}}}

Cancel the {{{(x+2)}}}'s

{{{matrix(1,1,
((cross(x-3))(cross(x+3))(x-2)(cross(x+2)))/((cross(x+2))(cross(x-3))(cross(x+3))))}}}

All that's left is

{{{x-2)}}}
