Question 984481


The fact that &nbsp;{{{x-1}}}&nbsp; is a factor of &nbsp;{{{4x^3 + 3x^2 - 4x  + k}}}&nbsp; means that &nbsp;<B>1</B>&nbsp; is the root of this polynomial, &nbsp;i.e. 


{{{4*1^3 + 3*1^2 - 4*1 + k}}} = {{{0}}}.


It gives you &nbsp;k = -4 - 3 + 4 = -3.


<B>Answer</B>. &nbsp;k = -3.
