Given the expression: 7x+63 a) What is the greatest common factor (GCF)? b) Write the expression in factored form.

darkknight:

What do you think is the GCF? as a hint, what can u factor out of 7x and 63?

darkknight:

still with me?

darkknight:

Both terms do not have a variable, so we can't factor out x. Now it must be a number we can factor out of both 7x and 63. Ill give a hint, what happens if 7 is factored out, do u think it is possible?

girlcode:

7x +63? sorry if this is confusing

darkknight:

it is not confusing, what happens if u factor out 7 from 7x+63, is it possible, is it the GCF
