Question

How do you multiply `(3x + 2)(4x - 5)`?

Answer 1

`12x^2 -7x -10`

Explanation:

Multiply each term with each other

1. `(3x) xx (4x) = 12x^2`
2. `(3x) xx (-5) = -15x`
3. `2 xx 4x = 8x`
4. `2 xx (-5) = -10`

So

`12x^2 -15x +8x -10`

`12x^2 -7x -10`

Answer 2

`12x^2-7x-10`

Explanation:

To multiply polynomials, you have to multiply the terms in the left by the terms on the right so multiply `3x` by `4x` and `-5` and do the same to `2`. You should get this once you're done:
`12x^2-15x+8x-10`

After you multiplied the polynomials, combine the like terms
`12x^2-7x-10`
