Помогите хоть половину сделать если не все

Answer 1

1.
$(h+i)^2 = h^2+2hi+i^2$
2.
$(u+r)(u-r) = u^2-ur+ur-r^2=u^2-r^2$
3.
$j^3-c^3 = (j-c)(j^2+jc+c^2)$
4.
$t^3+m^3 = (t+m)(t^2-tm+m^2)$
5.
$(3q+h)^3 = 27q^3+27q^2h+3qh^2+h^3$
6.
$(4m+5c)(4m-5c) = 16m^2-20mc+20mc-25c^2=16m^2-25c^2$
7.
$(6v+5f)(6v-5f) = 36v^2-30vf+30vf-25f^2=36v^2-25f^2$
8.
$(5t-3d)^2 = 25t^2-2*5*3td+9d^2=25t^2-30td+9d^2$
9.
$(x+3j)^3 = x^3+9x^2j+27xj^2+27j^3$
10.
$(2y-2g)^3 = 8y^3-12y^2g+12yg^2-8g^3$
11.
$(1-3b)^3 = 1-9b+27b^2+27b^3$
12.
$64-y^3= 4^3-y^3=(4-y)(4^2+4y+y^2) = (4-y)(16+4y+y^2)$
13.
$8+27x^3 = 2^3+3^3x^3= (2+3x)(2^2-6x+3^2x^2) = (2+3x)(4-6x+9x^2)$
14.
$1-27j^3 = 1^3-3^3j^3 = (1-j)(1^2+3j+3^2j^2)= (1-j)(1+3j+9j^2)$
15.
$(2w-4)^3 = 8w^3-48w^2+96w-64$
16.
$(22+5w)^2 = 484+2*22*5w+25w^2=484+220w+25w^2$
17.
$(s+2w)^3 = s^3+6s^2w+12sw^2+8w^3$
18.
$64r^3+27x^3 = 4^3r^3+3^3x^3=(4r+3x)(4^2r^2-12rx+3^2x^2)=(4r+3x)(16r^2-12rx+9x^2)$
19.
$64c^3+1 = 4^3c^3+1^3=(4c+1)(4^2c^2-4c+1^2)=(4c+1)(16c^2-4c+1)$
20.
$125g^3+216= 5^3g^3+6^3=(5g+6)(5^2g^2-30g+6^2)=(5g+6)(25g^2-30g+36)$
21.
$(9+5y)^3 = 729 + 3*81*5y+25y^2*3*9+ 125y^3=729+1215y+675y^2+125y^3$
22.
$(19+17x)^2=361+2*19*17x+289x^2=361+646x+289x^2$
23.
$(5x+9)^3=125x^3+3*25x^2*9+3*5x*81+9^3=125x^3+675x^2+1215x+729$
24.
$(23r-23)(23+23r) = (23r-23)(23r+23) = 23r^2-23^2=23r^2-529$
25.
$512+216i^3=8^3+6^3j^3=(8+6i)(8^2-8*6i+6^2i^2)=(8+6i)(64-48i+36i^2)$
