(2x-7)(3x+4)
= (2x-7)*3x + (2x-7)*4
= (6x^2-21x) + (8x-28)
= 6x^2-13x -28
i dont understand what you mean by foil

First Outside Inside Last
(2x)(3x)= 6x squared
(2x)(4)= 8x
(-7)(3x)= -21x
(-7)(4)= -28
6x squared + 8x - 21x -28= (gather like terms)
Answer: 6x squared - 13x - 28
If you draw curved lines from the terms following the FOIL method, you get a figure that resembles a Nike swoosh. The visual is a good way to help you remember FOIL.

What is foil? Of course, the correct answer is (2x-7)(3x-4)= 6x^2-13x-28. This is simple algebra. If you need a more detailed answer, you have to tell me what does x equals to.

Woody has been playing with his woody too much! The correct expansion is: 6x^2 - 13x - 28, but for it to be an equation capable of being solved, it has to equal something.

multiply the first term in the first binomial and the first term in the second binomial and then the outside terms, then the inside terms, then the last terms in both binomials and add them all up
6x^2+8x-21x-28
6x^2-13x-28 is the final answer after simplified

(2x-7)(3x+4)
6x^2+8x-21x-28
6x^2-13x-28
That's the answer.

(2x - 7)(3x + 4) =
6x² - 21x + 8x - 28 =
6x² - 13x - 28

that depends on what they are supposed to be equal to...
(2x+7)(3x+4)=????
Or if you simply want to expand it out then 3x^2+29x+28
