Answer:
[tex]2 (15x + 14)[/tex]
Step-by-step explanation:
To factor, you have to find what number and/or variable they both have in common. Since, only 30x has a variable the gcf will not have an x in it, only a number. The only number 30 and 28 have in common are 2. So the GCF is 2. Then, in parenthesis, you have to write the remaining of the expression:
2 (15x + 14)
To make sure you're correct, solve it an you should get 30x + 28
