x^2-49
Improved Answer:-
It is: x2-49 = (x+7)(x-7) when factored which is the difference of 2 squares
A factor = a number which can be divided into the given number with no remainder ie 1, 7, 49 7 * 7 = 49
The GCF (Greatest Common Factor) of 49 and 343 is 49. Since 49 is a factor of 343, it is automatically the GCF.
A factor is a number that divides another number without leaving a remainder. In the equation 7x7=49, the number 7 is a factor because it divides evenly into 49, resulting in a whole number quotient of 7. Therefore, 7 is a factor of 49 in this case.
