How do you FOIL this math question

[From: ] [author: ] [Date: 12-05-14] [Hit: ]
there should be terms like,And also, the equation w2 + 7w + 4 = 0 cannot be factored..Therefore, there is no solution to the problem.......
w2(the 2 is squaring the w) + 7w + 4 = 0

I believe you are trying to solve the quadratic equation, not multiply two binomials. And since "FOIL" is a crutch to allow the rote multiplication of two binomials without requiring any understanding of the process, "FOIL" is not applicable to the problem presented.

w² + 7w + 4 = 0
w² + 7w = -4
w² + 7w + 49/4 = 49/4 - 16/4 = 33/4
(w + 7/2)² = 33/4
w + 7/2 = ±√33/2
w = (-7±√33)/2

-
w2 + 7w + 4 = 0

We cannot use FOIL in this math problem.
FOIL is multiplying the terms, NOT adding the terms ..
In foil, there should be terms like,
F - First terms
0 - Outer term or extremes
I - Inner terms or means and
L -Last terms or second terms

And also, the equation " w2 + 7w + 4 = 0 " cannot be factored..

Therefore, there is no solution to the problem.
