Question

28x-4 what is it factored

Answer 1

4(7x-1) this is how its factored :)

Answer 2

To factor 28x-4, find the LCD
(find the number that can equal to both 28 and -4)

In this case, it would be 4. So, you factor out 4 from the equation

and it would look like 4* (7x-1)

You can not simplify it any more so the answer would be 4(7x-1)
