Simplify (2x+1)(x-5)

$(2 x + 1) (x - 5)$

Step 1

Expand $(2 x + 1) (x - 5)$ using the FOIL Method.

Apply the distributive property.

$2 x (x - 5) + 1 (x - 5)$

Apply the distributive property.

$2 x \cdot x + 2 x \cdot - 5 + 1 (x - 5)$

Apply the distributive property.

$2 x \cdot x + 2 x \cdot - 5 + 1 x + 1 \cdot - 5$

$2 x \cdot x + 2 x \cdot - 5 + 1 x + 1 \cdot - 5$

Step 2

Simplify and combine like terms.
