(x-1)(x-2)(x-3)(x-4)-48
=x^2 -2x-x +2 +x^2 -3x-2x +6 +x^2 -4x-3x +12-48
=x^2+x^2+x^2 -2x-x-3x-2x-4x-3x +2+6+12-48
=3x^2-15x-28
=x^2 -2x-x +2 +x^2 -3x-2x +6 +x^2 -4x-3x +12-48
=x^2+x^2+x^2 -2x-x-3x-2x-4x-3x +2+6+12-48
=3x^2-15x-28

=(x^2-3x+2)(x^2-7x+12)-48
=x^4-10x^3+35x^2+50x+24-48
=x^4-10x^3+35x^2+50x-24
yeah!
=x^4-10x^3+35x^2+50x+24-48
=x^4-10x^3+35x^2+50x-24
yeah!

(4x)+(-1-2-3-4)-48
ANS==(4x)+(-10)-48
Wrong la ,me think
ANS==(4x)+(-10)-48
Wrong la ,me think

可能是這樣:
(x-1)(x-2)(x-3)(x-4)-48
=(x)(x)(x)(x)+(-1)(-2)(-3)(-4)-48
=x^4+24-48
=x^4-24

(x-1)(x-2)(x-3)(x-4)-48
