x2 - 14x + 49(x - 7) (x - 7)
(x - 3)(x - 11)
-x2-14x-45 = -(x2+14x+45) delta = 142-4*1*45=16 so x2+14x+45=(x-(-14+4)/2) (x-(-14-4)/2) = (x+5)(x+9) so -x2-14x-45 = -(x+5)(x+9)
The roots are: x = -5 and x = -9
It is not possible to give a sensible answer to this question. The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers or expressions. You have only one expression in the question!
-x2+14x=49
x2 - 14x + 49(x - 7) (x - 7)
x2 - 14x + 49 = (x - 7)2
x2+14x+49 = (x+7)(x+7) when factored

49 x2 + 14x = -7 x2 + 14x + 49 = 42 (x + 7)2 = 42 x = -7 ± √42
x2 - 14x = -49 ∴ x2 - 14x + 49 = 0 ∴ (x - 7)2 = 0 ∴ x = 7
(x-7) (x-7)
Yes because if x2-14x+49 then it is (x-7)(x-7) when factored
