    Re: Factoring trinomial

    I guess the second degree polynomial has to be: x^2+5x+4, in that case your answer is correct.

    I'm sorry to bother you but I'm know on my second set , and the instructions are (Factor the trinomial. If the trinomial cannot be factored say so.).

    The Trinomial is 2x^2+7x+3

    I tried (2X+1)(X+3) But obviously there wasn't even a point to try that.

    Re: Factoring trinomial

    You're not bothering me . And your answer is correct again. You can check it by yourself by expanding: (2x+1)(x+3)=2x^2+x+6x+3=2x^2+7x+3 which is the given polynomial.

    Sorry for my lack of understanding and communicating in english but therefore it cannot be factored since 3+1 is 4?

    Re: Factoring trinomial

    You don't have to excuse and 3+1 is indeed 4 but in this case it's 3x1 which is 3.

    But doesn't it also have to be equal to 7 when you add it?
    or since there is a coefficient on the x^2 the rules change?
