Find the Product (x+5)(x+4)

$(x + 5) (x + 4)$

Step 1

Expand $(x + 5) (x + 4)$ using the FOIL Method.

Apply the distributive property.

$x (x + 4) + 5 (x + 4)$

Apply the distributive property.

$x \cdot x + x \cdot 4 + 5 (x + 4)$

Apply the distributive property.

$x \cdot x + x \cdot 4 + 5 x + 5 \cdot 4$

$x \cdot x + x \cdot 4 + 5 x + 5 \cdot 4$

Step 2

Simplify and combine like terms.

Simplify each term.

Multiply $x$ by $x$ .

$x^{2} + x \cdot 4 + 5 x + 5 \cdot 4$

Move $4$ to the left of $x$ .

$x^{2} + 4 \cdot x + 5 x + 5 \cdot 4$

Multiply $5$ by $4$ .

$x^{2} + 4 x + 5 x + 20$

$x^{2} + 4 x + 5 x + 20$

Add $4 x$ and $5 x$ .

$x^{2} + 9 x + 20$

$x^{2} + 9 x + 20$
