    Setting it up like this makes it alot easier: (6x2+ 11x – 3) (2x2– 17x – 4)

    6x2 + 2x2 = 8x2 11x - 17x = -6x -3 - 4 = -7

    6x2+ 2x2=8x2 and 11x – 17x = -6x and – 3 – 4 = -7

    \[2x^2(4x^2+ 9x – 13)\] now we are multiplying

    so \[2x^2\] should multiply each item in the bracket

    almost there but notice that even the power changes \[2x^2(4x^2)=8x^{4}\]

    the powers add each other\[x^a(x^b)=x^{a+b}\]
