    Answer:

    Y= 2x^2+14x+12

    Explaination:

    When it gives you the roots you can automatically change the sign and put them with the x in factors such as

    y = (x+6)(x+1)

    Then you put the leading coefficient of 2

    y = 2(x+6)(x+1)

    Then to get it in standard form you distribute the parenthesis the the 2 to get:

    Y= 2x^2+2x+12x+12

    Combine like terms and you’ll answer will be

    Y= 2x^2+14x+12
