Question

Answer 1

1) \(\left(x+3\right)^3=x^3+9x^2+27x+27\)

2) \(\left(1+x\right)^3=1+3x+3x^2+x^3\)

3) \(\left(2-x\right)^3=8-12x+6x^2-x^3\)

4) \(\left(x-3\right)^3=x^3-9x^2+27x-27\)

5) \(\left(2x+1\right)^3=8x^3+12x^2+6x+1\)

6) \(\left(3x+2\right)^3=27x^3+54x^2+36x+8\)

Answer 2

7) \(\left(2x-3\right)^3=8x^3-36x^2+54x-27\)

8) \(\left(3x-1\right)^3=27x^3-27x^2+9x-1\)

9) \(\left(x+2y\right)^3=x^3+6x^2y+12xy^2+8y^3\)

10) \(\left(2x+y\right)^3=8x^3+12x^2y+6xy^2+y^3\)

11) \(\left(3x-y\right)^3=27x^3-27x^2y+9xy^2-y^3\)

Answer 3

12) \(\left(x-3y\right)^3=x^3-9x^2y+27xy^2-27y^3\)

13) \(\left(2x+3y\right)^3=8x^3+36x^2y+54xy^2+27y^3\)

14) \(\left(3x+2y\right)^3=27x^3+54x^2y+36xy^2+8y^3\)

15) \(\left(3x-2y\right)^3=27x^3-54x^2y+36xy^2-8y^3\)

16) \(\left(4x-y\right)^3=64x^3-48x^2y+12xy^2-y^3\)
