A= (5-2x)(x-4)
A=5x-20+2x²+8x
A=2x²+13x-20
B=(x-2)²+(3x+1)²
B=x²-4x+4+9x²+6x+1
B=10x²+2x+5
C=(x-1)²-(2x+5)²
C=x²-2x+1-(4x²+20x+25)
C=x²-2x+1-4x²-20x-25
C=-3x²-22x-24
D=x(x+1)(x-3)
D=x(x²-3x+x+3)
D=x^3-3x²+x²+3x
D=x^3-2x²+3x
A=5x-20+2x²+8x
A=2x²+13x-20
B=(x-2)²+(3x+1)²
B=x²-4x+4+9x²+6x+1
B=10x²+2x+5
C=(x-1)²-(2x+5)²
C=x²-2x+1-(4x²+20x+25)
C=x²-2x+1-4x²-20x-25
C=-3x²-22x-24
D=x(x+1)(x-3)
D=x(x²-3x+x+3)
D=x^3-3x²+x²+3x
D=x^3-2x²+3x
