Question

What is the product? 2 x (x minus 4)

Answer 1

Answer: Simplify the real and imaginary parts of the expression.

Answer is: 8x^2 minus

Answer 2

The product of 2x(x-4) is
`2x^2-8x`.

Explanation:

The given expression is

`2x(x-4)`

We need to find the product of 2x(x-4).

If a,b and c are three real numbers, then by distributive property

`a(b+c)\Leftrightarrow ab+ac`

Using distributive property, the given expression can be written as

`2x(x)+2x(-4)`

On simplification we get

`2x^2-8x`

Therefore the product of 2x(x-4) is
`2x^2-8x`.
