    Answer:

    2x square -25x + 7

    Step-by-step explanation:

    a square – (b+c)

    (3x-4)square – {(x+7)+(x square+2)}

    3x square-2.3x.4+4 square – (x+7+x square+2)

    3x square – 24x + 16 -x – 7 – x square – 2

    3x square – x square -24x – x + 16-7-2

    2x square-25x+7

    or,

    x(2x – 25)+7
