Question 187563
I was told to multiply this expression out, not sure how.
{{{(x+6)(x^3 - x^2 - 5x+1)}}}
----------------
Multiply {{{(x^3 - x^2 - 5x+1)}}} by x, then by 6, and add them up.
={{{x*(x^3 - x^2 - 5x+1) + 6*(x^3 - x^2 - 5x+1)}}}
={{{x^4 - x^3 - 5x^2 + x + 6x^3 - 6x^2 - 30x + 6}}}
={{{x^4 + 5x^3 - 11x^2 - 29x + 6}}}
