Question

What is the product
-9*(5-2x)

Answer 1

⇔ -45 + 18x

In-depth explanation:

Hi! We're asked to solve
`\textnormal{-9(5 - 2x)}`.

I am going to use the distributive property:

`\bf{a(b+c)=ab+ac}`

Similarly,

`\bf{-9(5-2x)}`

`\bf{-9*5-9*(-2x)}`

`\bf{-45 + 18x}`

∴ the answer is -45 + 18x

Answer 2

Answer: -45 + 18x

Explanation:

We will distribute the -9 into both of the other terms.

Given:

-9 * (5 - 2x)

-9(5 - 2x)

Distribute:

(-9 * 5) - (-9 * 2x)

Multiply:

-45 - (-18x)

Distribute the -1:

-45 + 18x

-45 + 18x or 18x - 45
