The problem is factoring completely
4xX^220x24
4(X^25x60
4(x6)(x+1)
12x^275
3(X^225)=3(X25)(x+3)
Can someone check these problem for me please.

The first one, second line should read 4(x^25x6). I think that's just a typo. For the 2nd one:
12x^275
3(x225)
3(x5)(x+5)

Andrew factored the expression 20x^312x^2+8x as 4x (5x^212x^2+8x). But when Melissa applied the distributive law and multiplied out 4x (5x^212x^2+8x), she got 20x^348x^3+32x^2; thus, Andrewâ€™s solution does not appear to check. …
