Answer 1

Answer:

$4x^2-25x-56$

Step-by-step explanation:

I'm not sure what your choices are, but I am assuming to need to simplify.

Here is how you do it:

(4x + 7)(x - 8) - Multiply 4x and x

     $4x^2$

(4x + 7)(x - 8) - Multiply 4x and -8

     -32x

(4x + 7)(x - 8) - Multiply 7 and x

     7x

(4x + 7)(x - 8) - Multiply 7 and -8

     -56

Now, add all of the terms together.

$4x^2$-32x+7x-56

    -32x+7x = -25x

$4x^2-25x-56$
