Question 6892
divide {{{2u^3-13u^2-8u+7}}} by (u-7) using long division, to give {{{2u^2 + u - 1}}}. This means that:


{{{(2u^3-13u^2-8u+7)/(u-7)}}} can be written as
{{{((u-7)(2u^2+u-1))/(u-7)}}}
{{{((u-7)(2u-1)(u+1))/(u-7)}}}
{{{(2u-1)(u+1)}}}


Now, your attempted answer is so very bad, William that i am nearly at a loss for words, and yet you must be in a fairly advanced stage of your maths studies, to be doing long division of polynomials. 


I would have to say that you understand very little of algebra if what you wrote is your true attempt. You need to sit with your teacher and get him/her to TEACH you the basics of algebra.
