Question

Simplify (x1/2 + y1/2 )(x1/2

-y

1/2).​

Answer 1

Answer:

(x^2 /4) -(y^2 /4)

Step-by-step explanation:

apply identity

(a+ b)( a-b)

Answer 2

Answer:

x-y

Step-by-step explanation:

we know that (a+b)*(a-b) = a^2-b^2

a=x^1/2 and b=y^1/2

substituting the values in above formula we get

(x^1/2+y^1/2)*(x^1/2-y^1/2) = x-y
