(6t^2+11)(6t^2-11) I think I'm overthinking, but is this 0? Or do have to multiply them? If so, is 6t^2 multiplied by itself 36t^2 or 36t^4? (6t^2+11)(6t^2-11)

    Remember the acronym F.O.I.L (first, outside, inside, last)

    i'm not trying to confuse you here but technically most quadratics = 0. so 'it is 0' :)
