No, 13 is not a factor of 179. One way to tell is to divide 179 by 13, the quotient is not a whole number, so it is not a factor. Another way to tell is to see that 13 times thirteen is 169, so if 179 were a factor it would be 13 away from 169. Since 179 minus 169 is 10, 179 is not a factor.
2(x - 13)(x + 13)
These factor pairs, when multiplied, equal 273: (1, 273) (3, 91) (7, 39) (13, 21)
The numbers below are the factor pairs of 130 (multiplied together they equal 130) (1, 130) (2, 65) (5, 26) (10, 13)
The numbers below in parentheses are the factor pairs of 130. Multiplied together they will equal 130: (1, 130) (2, 65) (5, 26) (10, 13)
8 plus 1 times 12 minus 13 is equal to seven.
Three minus three times six plus two is equal to -13.
-8 - (-13) = - 8 + 13 = +5 ( minus a minus is a plus)

13 times 43560 is equal to 566280.
25 + 16 - 13 - 21 = 7
Seven minus -6 is 13.
One minus fourteen, 1-14 equals -13 read as negative 13.
Since 8 does not equal 13 - 4the equation (8 = 13 - 4) is false and so (8 = 13 - 4) = 0
