Answer:

Step-by-step explanation:
To factor the expression, remove the greatest common factor or GCF from each term. Both terms share in common xy. The expression becomes:

What remains in the parenthesis is a different of perfect squares. Factor the difference of perfect squares into two binomials of the form (x+a)(x-a) where a is the square root of
.
So the expression becomes:

Using: A^2+b^2=c^2
A&b= (√10)^2=10
10+10=c^2
20=c^2
(take the square root of 20)
c=2√5
Your answer is D
