Simplify (x+5)(x-3)

$(x + 5) (x - 3)$

Step 1

Expand $(x + 5) (x - 3)$ using the FOIL Method.

Apply the distributive property.

$x (x - 3) + 5 (x - 3)$

Apply the distributive property.

$x \cdot x + x \cdot - 3 + 5 (x - 3)$

Apply the distributive property.

$x \cdot x + x \cdot - 3 + 5 x + 5 \cdot - 3$

$x \cdot x + x \cdot - 3 + 5 x + 5 \cdot - 3$

Step 2

Simplify and combine like terms.

Simplify each term.

Multiply $x$ by $x$ .

$x^{2} + x \cdot - 3 + 5 x + 5 \cdot - 3$

Move $- 3$ to the left of $x$ .

$x^{2} - 3 \cdot x + 5 x + 5 \cdot - 3$

Multiply $5$ by $- 3$ .

$x^{2} - 3 x + 5 x - 15$

$x^{2} - 3 x + 5 x - 15$

Add $- 3 x$ and $5 x$ .

$x^{2} + 2 x - 15$

$x^{2} + 2 x - 15$
