Andrew factored the expression 20x^3-12x^2+8x as 4x(5x^2-12x^2+8x) but when melissa applied the distributive law and multiplied out 4x(5x^2-12x^2+8x)she got 20x^3-48x^3+32x thus Andrews solution does not appear to check. Why is that? Please help Andrew to understand this better. Explain your answer reasoning and correctly factor the original expression if possible. If the expression is prime so state.

Should have been

4x(5x^2 - 3x + 2)
