You have the following expression:
4t - 8
to factorize the previous expression, take into account that the greatest common divisor of coefficients 4 and 8 is 4. Divide each term by 4 and put the result inside parenthesis, preceeded by 4, just as follow:
4t - 8 =
4(4t/4 - 8/4) =
4(t - 2)
Hence, the factorized expression is
A: 4(t -2)
C: (t - 2)4
