2) a³ + 2a - a² + 3a² - 10a² + 5 = a³ +2a - 8a² + 5
3) 3b + ( b + 1 ) = 3b + b + 1 = 4b +1
4) 5a - ( a + 1 ) = 5a - a - 1 = 4a - 1
5) 2a + ( 3a - 2b ) + ( a + b ) = 2a + 3a - 2b + a + b = 6a - 1b
6) 5a - ( 2 - x ) - 5 - ( 2x - 5 ) = 5a - 2 + x - 5 - 2x + 5 = 5a - 2 - x
Liczę na naj :)
2) a³+2a-a²+3a²-10a²+5= a³+2a-8a²+5
3) 3b+(b+1)= 3b+b+1= 4b + 1
4) 5a-(a+1) = 5a-a-1 = 4a-1
5) 2a+(3a-2b)+(a+b) = 2a+3a-2b+a+b = 6a-b
6) 5a-(2-x)-5-(2x-5) = 5a-2+x-5-2x+5 = 5a-2-x
