matymatyka 7 klasa szybko pls​

Answer 1

(2xy+3)2 + 4x•2 = 4xy+6+8x = 4xy+8x+6

c) (7y-3x)2 + (x+y)2 = 14y-6x+2x-2y = 12y-4x

d) (8a+3b)2 + (a-2b)2 = 16a+6b+2a-4b = 18a+2b

e) (4x-y)2 + (x+y)2 = 8x-2y+2x+2y = 10b) (2xy+3)2 + 4x•2 = 4xy+6+8x = 4xy+8x+6

c) (7y-3x)2 + (x+y)2 = 14y-6x+2x-2y = 12y-4x

d) (8a+3b)2 + (a-2b)2 = 16a+6b+2a-4b = 18a+2b

e) (4x-y)2 + (x+y)2 = 8x-2y+2x+2y = 10x

Mam nadzieję ze pomogłam i licze na naj :)
