    Expanding those brackets out precisely gives u : -9x-12+3x^2+4x which cancels out to what u got except for it ending up resulting in a negative 5x as it would cancel out to get 3x^2-5x-12
    Yes you are right - and that was the question I had a typo

    Wasn't the last question like 1/2 * 7 * 8 Sin(X) = 18


    56Sin(x) = 36

    Sin^-1(36/56) = X

    x = 40

    ???

    I think I did it wrong then.

    -9x-12 +3x^2 +4
    3x^2 -9x -8

    I think you meant to put +4x at the end there mate proving I am right

    I got 80.1? You're probably right. Did you get the other angle as 40 and side as 5.22?
    You rounded too early
    The angle was 40.00520088
    The side was 5.216 etc.
