Question

СРОЧНО, ПОЖАЛУЙСТА.​

Answer 1

Пошаговое объяснение:

1. (d+1)^2=d^2+2d+1
2. (b-9)^2=b^2-18b+81
3. (8+p)^2=64+16p+p^2
4. (-p+q)^2=p^2-2pq+q^2
5. (4-7n)^2=16-56n+49n^2
6. (2+8c)^2=4+32c+64c^2

Answer 2

а) $\displaystyle \tt (d+1)^2=d^2+2d\cdot1+1^2=\bold{d^2+2d+1}$

б) $\displaystyle \tt (b-9)^2=b^2-2b\cdot9+9^2=\bold{b^2-18b+81}$

в) $\displaystyle \tt (8+p)^2=(p+8)^2=p^2+2p\cdot8+8^2=\bold{p^2+16p+64}$

г) $\displaystyle \tt (-p+q)^2=(q-p)^2=\bold{q^2-2pq+p^2}$

д) $\displaystyle \tt (4-7n)^2=4^2-2\cdot4\cdot7n+(7n)^2=\bold{16-56n+49n^2}$

е) $\displaystyle \tt (2+8c)^2=2^2+2\cdot2\cdot8c+(8c)^2=\bold{4+32c+64c^2}$
