Answer 2

Step-by-step explanation:

if the question is (x-5)^2/25-x^2

x^2+25-10x/25-x^2............. (1)

factorizing x^2-10x+25

x^2-5x-5x+25

x(x-5)-5(x-5)

(x-5)(x-5)..................(2)

substituting (2) in (1)

(x-5)(x-5)/25-x^2

since 25-x^2 can be written as 5^2-x^2=

(5-x)(5+x)........ using identity

(x-5)(x-5)/-(x-5)(5+x)

cancelling (x-5)

(x-5)/-(5+x)

(5-x)/(5+x)

dividing (5-x) by (5+x)

-2x
