The highlighted variables a = 6 , b = 2, c=6 , d =2 , e=6 , f =6 , g =1
An expression is a mathematical statement which consists of variables , constants and mathematical operators.
[tex]\rm \dfrac{2}{x^2-36}-\dfrac{1}{x^2+36}\\= \dfrac{2}{(x+6)(x-6)}-\dfrac{1}{x(x+a)}\\=\dfrac{bx}{x(x+6)(x-6)}-\dfrac{x-c}{x(x+6)(x-6)}\\\\=\dfrac{dx-x+e}{x(x+6)(x-6)}\\\\= \dfrac{x+f}{x(x+6)(x-6)}\\\\=\dfrac{g}{x(x-6)}[/tex]
In the given expression
a = 6 , b = 2, c=6 , d =2 , e=6 , f =6 , g =1
