Question

Умоляю помогите с алгеброй

Answer 1

2. 8+a^3=2^3+a^3=
(2+a)(4-2a+a²) отв. а

3. 8x^3-1=2^3x^3-1=
=(2x-1)(4x²+2x+1) отв. б

4. (4x+3y)(16x²-12xy+9y²)
ответ б

5. (0.5x-0.1y)(0.25x²+ +0.05xy+0.01y²) отв. в

6. x^3-y^6=
=(x-y²)(x²+xy²+y^4) отв. а

7. (1/2-a²)(1/4+1/2a²+a^4)
отв. б

Answer 2

2. 8+а³=2³+а³=(2+а)(4-2а+а²); 3. 8х³-1=(2х)³-1³=(2х-1)(4х²+2х+1); 4. 64х³+27у³=(4х)³+(3у)³=(4х+3у)(16х²-12ху+9у²); 5. 0,125х³-0,001у³=(0,5х)³-(0,1у)³=(0,5х-0,1у)(0,25х²+0,05ху+0,01у²); 6. х³-у^6=(х-у²)(х²+ху²+у⁴); 7.-а^6+1/8=(1/2)³-(а²)³=(1/2-а²)(1/4+1/2а+а⁴)
