    \[\huge\rm qoutient + \frac{ remainder }{ divisor }\] quotient = q(x) remainder = r(x) divisor = b(x)

    are you sure? leading coefficient of divisor is one so you do synthetic division which is really easy

    x^2 -4x+1 is the solution the the equation in the photo, right?

    thank you so much ive been trying to figure out what q(x), r(x), and b(x) stood for forever

    alright for synthetic division x-3=0 solve for x x=3 write JUST coefficient |dw:1433942314956:dw| carry down first number and then multiply by 3

    |dw:1433942396062:dw| multiply and then combine like terms -7 +1 = -6 multiply again

    The upper one is a cubic equation, but worry not and be smart about it. Notice that you have to divide the whole thing to (x-3) so there's a good chance 3 is a root for that cubic equation. Checks out it is. Divide the cubic one to (x-3) and you'll get your answer. Alternatively, you can be smart about that too and notice that (x^2-4x+1) is the only thing that makes sense since it's the only quadratic form (which you'd expect to have if you divide a cubic equation to a linear one) that "allows" for that -3 at the cubic equation to be formed. The other quadratic (the one with +13) when multiplied with (x-3) will give you something with -39 at the end so that's no good.

    So you can conclude that it divides evenly and that your answer is q=(x^2-4x+1) r=0 b=*could be just about anything but for the sake of math* x-3
