Answer:
[tex]4x^2-25x-56[/tex]
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
[tex]4x^2[/tex]
(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.
[tex]4x^2[/tex]-32x+7x-56
-32x+7x = -25x
[tex]4x^2-25x-56[/tex]
