Question

Which expression is equivalent to ( xy -6)2 for all values of x and y where the expression is defined?

Answer 1

xy^36

Explanation:

Answer 2

( x y -6)² = x² y² - 12 xy + 36

Explanation:

Explanation:-

Given that the expression ( x y -6)²

Apply formula (a-b)² = a² -2ab + b²

( x y -6)² = (xy)² - 2 × xy× 6 + (6)²

= x² y² - 12 xy + 36

( x y -6)² = x² y² - 12 xy + 36
