Question 182728
{{{(x^2 - 3x + 5)(x + 9)}}}
{{{x^3 - 3x^2 + 5x + 9x^2 - 27x + 45}}}
{{{x^3 - 3x^2 + 9x^2 + 5x - 27x + 45}}}
{{{x^3 + 6x^2 - 22x + 45}}}
---------------------------
I use a quick little check: suppose {{{x = 3}}} (or any number)
{{{(x^2 - 3x + 5)(x + 9)}}}
{{{(9 - 9 + 5)*12 = 60}}}
and
{{{x^3 + 6x^2 - 22x + 45}}}
{{{27 + 54 - 66 + 45 = 60}}}
OK
