Andrews factored expressions
-6x63+9x^2-3x as -3x(2x^2-3x-1). But when Melissa applied the distrubutive law and multiplied out -3x(2x62-3x-1) 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.
