Question

Doprowadz do najprostrzej postaci:

c) 5+(4y-6)-(y+2)=

d) (6w-2y+2)(-4) =

e) 2(b-5a)-a(3b+a)=

F) (2a-5) (a+4)=

Answer 1

a) 5+4y-6-y-2=-3+3y
b) 24w-8y-8
c)2b+10a-3ab-a2

Answer 2

c) 5+(4y-6)-(y+2)=5+4y-6-y-2=3y-3



d) (6w-2y+2)(-4) =-24w+8y-8



e) 2(b-5a)-a(3b+a)=2b-10a-3ab-a²=-a²-10a+2b-3ab



F) (2a-5) (a+4)=2a²+8a-5a-20=2a²+3a-20
