a)5a(2x-3)+4*(2x-3)+
b)6c(c+1)-6*(c=1)= c)2x[kwadrat]*(x+2)-6*(c+1)= d)-4x(4x-1)-x(-1=4x)= e)-7x(x+3)-(3+x)= Proszę mam to na dzisiaj!!!

a) 5a(2x-3)+4*(2x-3)=10ax+15a+8x+12
b)6c(c+1)-6*(c-1)=6c[kwadrat]+6-6c+6=6c[kwadrat]-6c+12
c)2x[kwadrat]*(x+2)-6*(c+1)=2x[dotrzeciej]+4x[kwadrat]-6c-6
d)-4x(4x-1)-x(-1-4x)=-8x[kwadrat]+4x+x+4x=-8x[kwadrat]+x+8x[kwadrat]=x
e)-7(x+3)-(3+x)=-7x-21(3+x)=-7x-63-21x=-63-28x
