haha no fair well its multiple choice...just distribute each option and see if its correct

anonymous · Answer

so for x squared term, you can only have 1 and 3 to yield 3. And for a constnat term ( that one with no letter beside) can have only 1 and 4 to yield 4. one of the two numbers from x term multiplied by one of the number on y term is added to another number from the x term multiplied by another term of the y term to give 13.

and when you do that, you get (3x+1)(x+4)
