Which binomial is equivalent to (xy + z)(xy − z)?
a) x2y2 + z2
b) x2y − z2
c) x2y2 − z2
d) x2y + z2

x2y2 - z2

Step-by-step explanation:

multiple each expression one by one

(xy + z)(xy - z) = x^2y^2 - xzy + xzy -z^2 ➡ +xzy will eliminate -xzy

and only x^2y^2 - z^2 will be left

to rewrite a literal equation you may need to divide by a number, or by a variable.
