Simplify (6x-y)^2

${(6 x - y)}^{2}$

Step 1

Rewrite ${(6 x - y)}^{2}$ as $(6 x - y) (6 x - y)$ .

$(6 x - y) (6 x - y)$

Step 2

Expand $(6 x - y) (6 x - y)$ using the FOIL Method.

Apply the distributive property.

$6 x (6 x - y) - y (6 x - y)$

Apply the distributive property.

$6 x (6 x) + 6 x (- y) - y (6 x - y)$

Apply the distributive property.

$6 x (6 x) + 6 x (- y) - y (6 x) - y (- y)$

Step 3

Simplify and combine like terms.

Simplify each term.

Rewrite using the commutative property of multiplication.

$6 \cdot 6 x \cdot x + 6 x (- y) - y (6 x) - y (- y)$

Multiply $x$ by $x$ by adding the exponents.

Move $x$ .

$6 \cdot 6 (x \cdot x) + 6 x (- y) - y (6 x) - y (- y)$

Multiply $x$ by $x$ .

$6 \cdot 6 x^{2} + 6 x (- y) - y (6 x) - y (- y)$

Multiply $6$ by $6$ .

$36 x^{2} + 6 x (- y) - y (6 x) - y (- y)$

Rewrite using the commutative property of multiplication.

$36 x^{2} + 6 \cdot - 1 x y - y (6 x) - y (- y)$

Multiply $6$ by $- 1$ .

$36 x^{2} - 6 x y - y (6 x) - y (- y)$

Rewrite using the commutative property of multiplication.

$36 x^{2} - 6 x y - 1 \cdot 6 y x - y (- y)$

Multiply $- 1$ by $6$ .

$36 x^{2} - 6 x y - 6 y x - y (- y)$

Rewrite using the commutative property of multiplication.

$36 x^{2} - 6 x y - 6 y x - 1 \cdot - 1 y \cdot y$

Multiply $y$ by $y$ by adding the exponents.

Move $y$ .

$36 x^{2} - 6 x y - 6 y x - 1 \cdot - 1 (y \cdot y)$

Multiply $y$ by $y$ .

$36 x^{2} - 6 x y - 6 y x - 1 \cdot - 1 y^{2}$

Multiply $- 1$ by $- 1$ .

$36 x^{2} - 6 x y - 6 y x + 1 y^{2}$

Multiply $y^{2}$ by $1$ .

$36 x^{2} - 6 x y - 6 y x + y^{2}$

Subtract $6 y x$ from $- 6 x y$ .

Move $y$ .

$36 x^{2} - 6 x y - 6 x y + y^{2}$

Subtract $6 x y$ from $- 6 x y$ .

$36 x^{2} - 12 x y + y^{2}$
