Пояснення:

1. 1) 2a(x-y)(x+y)

2) (5c-3d-3d)(5c-3d+3d)=5c(5c-6d)

2. (466+34)(466²-466x34+34²)=500(466²-466x34+34²)

Значення ділиться на 500

3. (49-29)²/(49-19)(49+19)=20²/30x68=10/51

4. x-y=17

x²-y²=799

(x-y)(x+y)=799

17(x+y)=799

x+y=799:17

x+y=47

y=47-x

x-(47-x)=17

2x=64

x=32

y=32-17=15

Он кормит белок шишками,
За стол садится с мишками,
С пушистыми зайчишками
Да с мышками-норушками!
Он делится орешками
С косулями, с олешками,
С кротами кропотливыми,
С бобрятами смешливыми.
