# How do you multiply 2(x+2) (x+5)?

Aug 17, 2015

Use FOIL for the last two, and then multiply everything by $2$

#### Explanation:

First:
$x \cdot x = {x}^{2}$
Outer:
$x \cdot 5 = 5 x$
Inner:
$2 \cdot x = 2 x$
Last:
$2 \cdot 5 = 10$

${x}^{2} + 5 x + 2 x + 10 = {x}^{2} + 7 x + 10$
Multiply by $2$
Answer$= 2 {x}^{2} + 14 x + 20$
