Please explain how to do #3

aleksley [76]

You answered correctly for part a. just simplify it. so for part a it would be x^4 + 8x^3 + 24x^2 + 32x + 16. repeat what you did in part a with part b (add & simplify). btw, the missing side in part c is 2x-x = x

$\dfrac{3x-1}{4}=-\dfrac{5}{11}\ \ \ \ |cross\ multiply\\\\11(3x-1)=4\cdot(-5)\\\\33x-11=-20\ \ \ \ |add\ 11\ to\ both\ sides\\\\33x=-9\ \ \ \ |divide\ both\ sides\ by\ 33\\\\x=-\dfrac{9}{33}\\\\\boxed{x=-\dfrac{3}{11}}$
