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

Answer:

$x^{2}y-z^{2}$

Step-by-step explanation:

Apply $(a+b)(a-b) = a^{2} -b^{2}$ where $x\sqrt{y}$ is $a$ and $z$ is $b$.

$(x\sqrt{y} )^{2}-z^{2}$

$(x\sqrt{y} )^{2}=x^{2}y$

$x^{2}y-z^{2}$

Hope this helps! :]
