Andrews factored expressions
6x63+9x^23x as 3x(2x^23x1). But when Melissa applied the distrubutive law and multiplied out 3x(2x623x1) she got 6x^3+9x^2+3x;thus Andrews solution does not appear to check. Why is that? Please help Andrews to understand this better, explain yout reasoning and correctly factor the orginal expression. If possible, if expression is prime, state this.
