    -16x^2 + 9

    Step-by-step explanation:

    To start this problem I would rearrange so that the terms with the x's come first. Making it look like this

    (4x+3) (-4x+3)

    Now you take the 4x and distribute it to the - 4x and the 3.

    -16x^2+12x This is the first part

    Take the 3 and distribute it to the - 4x and the 3 as well.

    -12x+9

    All you do now is combine the twoso you'd have

    -16x^2 + 12x - 12x + 9 Notice there are two terms that have a regular x with no exponent. This means you can combine them to simplify further.

    -12x+12x=0 So you no longer have to include this term in your answer.

    -16x^2+9 Would then be your final answer.
