Algebra

Can someone help me with this please.
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.

  1. Andrew divided only the first term by 4x.

    Should have been

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

    Megan factored the expression -12x^2 +52x-35as (-2x+5)(6x-7). But when Jacob applied the FOIL principle and multiplied out (-2x+5)(6x-7), he got -12x^2+44x-35; thus, Megan’s solution does not appear to check. Why is that?
