Question

Find product simplified form: (x√y + z) (x√y - z)

x^2y - z^2
x^2y + 2zx√y - z^2
x^2y - 2^2
x^2y^2 - z^2

Answer 1

I really want to thank you for the answer and explanation.

Answer 2

`x^(2)y-z^(2)`

Explanation:

Apply
`(a+b)(a-b) = a^(2) -b^(2)` where
`x√(y)` is
`a` and
`z` is
`b`.

`(x√(y) )^(2)-z^(2)`

`(x√(y) )^(2)=x^(2)y`

`x^(2)y-z^(2)`

Hope this helps! :]
