Show that x + 2c is a factor of f (x) = xcubed + 7cxsquared + 11csquared(x) + (2c)cubed, c a constant, and find the three roots of f(x) = 0.
Can someone show how to do this q please. Thanks!

hi
if $\displaystyle x+2c$ is a factor of $\displaystyle f$,then $\displaystyle -2c$ is a root of $\displaystyle f$.
