Answer 6

Since you have 3x^2 as the squared term you know that the two numbers that have an x in front of them are going to be 1 and 3. so one side will be 3x+something and one side will be x+something. then u just find 2 numbers that multiply to make the last term (5 and 2) and plug them into the equation and find a spot where they make sense.
