<span>f '(x) = [(-40x +11)(7x - 9) - 7(-4x +3)(5x + 1)]/(7x - 9)2</span>
<span>= [(-280x2<span> + 360x + 77x - 99) - 7(-20x</span>2<span> - 4x + 15x + 3)]/(7x - 9)</span>2</span>

<span>= (-140x2<span> +360x - 120)/(7x - 9)</span><span>2
</span></span>
i think thats how you would solve it
hope this helps tho:)
