(x - y + 7)(x + y)
(3b + 7x)(3b + 7x) or (3b + 7x)2
7 x3 + 2 x = x (7 x2 + 2)
-2x+7x=5x. Factor out the x. -2+7 I hope you know how to use a calculator. :D
In 7x+7, x is a variable.
x(5x + 7)
It is: 7(x+2y)
7(x + 4)
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.
(7x - 8)(2x - 7)
7x2 + 7x - 14 = 7(x2 + x - 2) = 7(x + 2)(x - 1)
(x - y + 7)(x + y)
(x + 7)(x2 - 7x + 49)
If you mean: 7x+91 then it can be factored to 7(x+13)
(3b + 7x)(3b + 7x) or (3b + 7x)2
7 x3 + 2 x = x (7 x2 + 2)
-2x+7x=5x. Factor out the x. -2+7 I hope you know how to use a calculator. :D
