Answer:

2
x^(2)+x-28

Explanation:

To solve binomial multiplication problems you can use the FOIL method. FOIL means first, outside, inside, last, which tells you what order to multiply the terms.

Multiply the first terms,

(2x-7)(x+4)

2
x^(2)

Then the outside terms,

(2x−7)(x+4)

8x

Next the inside terms,

(2x−7)(x+4)

-7x

Finally the last terms,

(2x−7)(x+4)

-28

To find the answer put all of the products together and simplify

2
x^(2)+8x-7x-28

2
x^(2)+x-28
