Question

Please help me. Multiply. (x−5)(3x+6) Express the answer in standard form. Enter your answer in the box.

Answer 1

`3x^2-9x-30`

Explanation:

Use the FOIL method to solve:

First:
`x*3x=3x^2`

Outer:
`x*6=6x`

Inner:
`-5*3x=-15x`

Last:
`-5*6=-30`

Combining them all, we get:

`3x^2+6x-15x-30=\\3x^2-9x-30`

Answer 2

3x² - 9x - 30

Explanation:

We use FOIL to multiply (First, Outside, Inside, Last)

Step 1: F

3x²

Step 2: O

6x

Step 3: I

-15x

Step 4: L

-30

Step 5: Rewrite

3x² + 6x - 15x - 30

Step 6: Combine like terms

3x² - 9x - 30
