Find the Product (4xy-3z)^2

${(4 x y - 3 z)}^{2}$

Rewrite ${(4 x y - 3 z)}^{2}$ as $(4 x y - 3 z) (4 x y - 3 z)$ .

$(4 x y - 3 z) (4 x y - 3 z)$

Expand $(4 x y - 3 z) (4 x y - 3 z)$ using the FOIL Method.

Apply the distributive property.

$4 x y (4 x y - 3 z) - 3 z (4 x y - 3 z)$

Apply the distributive property.

$4 x y (4 x y) + 4 x y (- 3 z) - 3 z (4 x y - 3 z)$

Apply the distributive property.

$4 x y (4 x y) + 4 x y (- 3 z) - 3 z (4 x y) - 3 z (- 3 z)$
