7(x + 1)
7x + 7 = 7(x + 1)
It is 7(-x -5) when factored
(7x + 5)(2x - 7)(2x-7)(7x+5)

To factor the trinomial (7x^2 + 7x - 14), first factor out the common factor of 7: [ 7(x^2 + x - 2) ] Next, we can factor the quadratic (x^2 + x - 2) into ((x + 2)(x - 1)). Thus, the complete factorization of the original trinomial is: [ 7(x + 2)(x - 1) ]
7x + 7 = 7(x + 1)
Factoring requires you to reduce as much as possible. To factor 7x + 49, you remove the common factor of 7x and 49, which is 7, and multiply (7x + 49)/7 (which is x + 7) by 7, without actually simplifying. 7x + 49 = 7(x + 7) Then, if possible, do the same thing until it cannot be further factored.
7(x - 2y)
The GCF is 7.

It is: 7(x+2y)
x(5x + 7)
The GCF is 7.
7(x + 4)
The GCF is 7.
It is 7(-x -5) when factored
Look for the GCF. 7, 14 and 21 all have 7 as a common factor. Divide that out. 7x divided by 7 = x 21 divided by 7 = 3 14y divided by 7 = 2y 7x + 21 + 14y = 7(x + 3 + 2y)
