Question

Distribute 6x (1 + x).

Answer 1

The distributive rule: "To multiply a sum by a number, multiply each term of the sum"

`m\cdot(a\text{ + b) = m}\cdot a\text{ + m}\cdot b`

We have to:

`6\cdot x\cdot\text{ (1 }+x\text{) = 6}\cdot x+6\cdot x^2\text{ }`

The answer is:

`6\cdot x\text{ }+\text{ 6}\cdot x^2`
