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

-2x+7x=5x. Factor out the x. -2+7 I hope you know how to use a calculator. :D
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.

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)
x(5x + 7)
It is: 7(x+2y)
7(x + 4)
The GCF is 7.
The GCF is 7.
It is 7(-x -5) when factored
