Bonjour,
C = [tex]2t(3-4t)-(5-a)+(9t+2)(3t-3)[/tex]
C = [tex]6t - 8t^{2} - 5 + a + 27t^{2} -27t+6t-6[/tex]
C = [tex]6t -27t +6t- 8t^{2} + 27t^{2} + a -6 - 5[/tex]
C = [tex]-15t + 19t^{2} + a -11[/tex]
D = [tex]-(5-2z)(z-8)[/tex]
D = [tex]-(5z-40-2z^{2} +16z)[/tex]
D = [tex]-(21z-40-2z^{2})[/tex]
D = [tex]-21z+40+2z^{2})[/tex]
E = [tex]-2s(2-s)+(-s-2)(s+5)[/tex]
E = [tex]-4s+2s^{2} + (-s^{2} -5s-2s-10)[/tex]
E = [tex]-4s+2s^{2} +(-s^{2} -7s-10)[/tex]
E = [tex]-4s+2s^{2} -s^{2} -7s-10[/tex]
E = [tex]-11s+s^{2} -10[/tex]
F = [tex](5x+8)(-3x-7)+(9x-4)(-10+2x)[/tex]
F = [tex]-15x^{2}-35x-24x- 56+(-90x+18x^{2} +40-8x)[/tex]
F = [tex]-15x^{2}-59x- 56-90x+18x^{2} +40-8x[/tex]
F = [tex]- 16-157x+3x^{2}[/tex]
G = [tex](3x-5)(-2x+1)-(5x-1)(3-4x)[/tex]
G = [tex]-6x^{2} +3x +10x -5 -(15x-20x^{2} -3+4x)[/tex]
G = [tex]-6x^{2} +3x +10x -5 -15x+20x^{2} +3-4x[/tex]
G = [tex]-6x -2 +14x^{2}[/tex]
H = [tex]-5(6x-4)(7x+2)+9x(8-x)(5x+4)[/tex]
H = [tex](-30x+20)(7x+2)+(72x-9x^{2} )(5x+4)[/tex]

I = [tex]-8(x+9y)-5(3y+5)(6-x)+8(3x-5y)[/tex]
I = [tex]-8x-72y+(-15y-25)(6-x)+24x-40y[/tex]
I = [tex]-8x-72y+(-90y+15yx-150+25x)+24x-40y[/tex]
I = [tex]-8x-72y-90y+15yx-150+25x+24x-40y[/tex]
