Answer:

option b
= ((x+1)(x+2))/(2)

Explanation:

Write the equation as:


(x^(2) -4x -5 )/(x-2) * (x^(2) -4)/(2x-10)\\\\= (x^(2) +x-5x -5 )/(x-2) * (x^(2) -2^(2) )/(2(x-5))\\\\= (x(x+1)-5(x+1) )/(x-2) * ((x+2)(x-2))/(2(x-5)) \; [use\;formula: \;a^(2) -b^(2) = (a+b)(a-b)]\\\\= ((x-5)(x+1))/(x-2) * ((x+2)(x-2))/(2(x-5))\\\\= ((x+1)(x+2))/(2)
