Find the Product (x+y)(2x-y)

$(x + y) (2 x - y)$

Expand $(x + y) (2 x - y)$ using the FOIL Method.

Apply the distributive property.

$x (2 x - y) + y (2 x - y)$

Apply the distributive property.

$x (2 x) + x (- y) + y (2 x - y)$

Apply the distributive property.

$x (2 x) + x (- y) + y (2 x) + y (- y)$

Simplify and combine like terms.

Simplify each term.

Rewrite using the commutative property of multiplication.

$2 x \cdot x + x (- y) + y (2 x) + y (- y)$

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

Move $x$ .

$2 (x \cdot x) + x (- y) + y (2 x) + y (- y)$

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

Rewrite using the commutative property of multiplication.

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

Rewrite using the commutative property of multiplication.

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

Rewrite using the commutative property of multiplication.

$2 x^{2} - x y + 2 y x - y \cdot y$

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

Move $y$ .

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

Multiply $y$ by $y$ .
