There is a formula for the "difference of squares." In this case, the answer is
(8x + 7)(8x - 7)
a + b + 4 is in its simplest form.
X(5-8)
8(7c - 5d)
ab(a - b)
To write 49 over 72 in simplest form, you need to find the greatest common factor (GCF) of 49 and 72, which is 1. Divide both the numerator and denominator by the GCF to simplify the fraction. Therefore, 49/72 in simplest form is 49/72.
(x-7)2
You can't know if a general polynomial is in factored form.
3y-6y in factored form = -3
56
252-70x+49 = (5x-7)(5x-7) when factored
I factored the other 49.
A completely factored form is one which is composed of product of factors and can't be factorized further. Let us consider two examples: x2 - 4x + 4 is not a factored form because it can be factored as (x - 2)(x - 2). (x +1)(x2 - 4x + 4) is also not a factored form because x2 - 4x + 4 can be factored further as (x - 2)(x - 2). So, the completely factored form is (x + 1)(x - 2)(x - 2).
x4-49 is the difference of two squares when factored as (x2-7)(x2+7)
It is: (x-7)(x+7) when factored
2(a+b) is 2a plus 2b in factored form.
x2+14x+49 = (x+7)(x+7) when factored
If you mean 4y+10 then it is 2(2y+5) when factored
