Sagot :

1.(x+1)³
=(x+1)²(x+1)
=(x²+2x+1)(x+1)
=x³+2x²+x+x²+2x+1
=x³+3x²+3x+1

2.(x+4)³
=(x+4)²(x+4)
=(x²+8x+16)(x+4)
=x³+8x²+16x+4x²+32x+64
=x³+12x²+48x+64

3.(x-6)³
=(x-6)²(x-6)
=(x²-12x+36)(x-6)
=x³-12x²+36x-6x²+72x+216
=x³-18x²+108x+216

4.(x-9)³
=(x-9)²(x-9)
=(x²-18x+81)(x-9)
=x³-18x²+81x-9x²+162x-729
=x³-27x²+243x-729

5.(x-1)³
=(x-1)²(x-1)
=(x²-2x+1)(x-1)
=x³-2x²+x-x²+2x+1
=x³-3x²+3x+1

6.(2x+5)³
=(2x+5)²(2x+5)
=(4x²+20x+25)(2x+5)
=8x³+40x²+25x+20x²+100x+125
=8x³+60x²+125x+125

7.(2x-5)³
=(2x-5)²(2x-5)
=(4x²-20x+25)(2x-5)
=8x²-40x²+50x-20x²+100x-125
=8x³-60x²+150x-125

8.(x+2y)³
=(x+2y)²(x+2y)
=(x²+4xy+4y²)(x+2y)
=x³+4x²y+4xy²+2x²y+8xy²+8y³
=x³+6x²y+12xy²+8y³

9.(2x-y)³
=(2x-y)²(2x-y)
=(4x²-4xy+y²)(2x-y)
=8x³-8x²y+2xy²-4x²y+4xy²-y³
=8x³-12x²y+6xy²-y³

10.(3x-1)³
=(3x-1)²(3x-1)
=(9x²-6x+1)(3x-1)
=27x³-18x²+3x-9x²+6x-1
=27x³-27x²+9x-1

11.(x-3)³
=(x-3)²(x-3)
=(x²-6x+9)(x-3)
=x³-6x²+9x-3x²+18x-27
=x³-9x²+27x-27

12.(5x-2)³
=(5x-2)²(5x-2)
=(25x²-20x+4)(5x-2)
=125x³-100x²+20x-50x²+40x-8
=125x³-150x²+60x-8

13.(2x+4)³
=(2x+4)²(2x+4)
=(4x²+16x+16)(2x+4)
=8x³+32x²+32x+16x²+64x+64
=8x³+48x²+96x+64

14.(3x+2y)³
(3x+2y)²(3x+2y)
=(9x²+12xy+4y²)(3x+2y)
=27x³+36x²y+4xy²+18x²y+24xy²+8y³
=27x³+54x²y+28xy²+8y³

15.(2x+3y)³
=(2x+3y)²(2x+3y)
=(4x²+12xy+9y²)(2x+3y)
=8x³+24x²y+9xy²+12x²y+36xy²+27y³
=8x³+36x²y+45xy²+27y³

Hope this helps =)
