Toán -(a-b+c)+(a-b+d) (a+b)-(-a+b-c) -(a+b)+(a+b+c) 15/07/2021 By Amaya -(a-b+c)+(a-b+d) (a+b)-(-a+b-c) -(a+b)+(a+b+c)
-(a-b+c)+(a-b+d) =-a+b-c+a-b+d =d-c (a+b)-(-a+b-c) =a+b+a-b+c =a+2c -(a+b)+(a+b+c) =-a-b+a+b+c =c Trả lời
-(a-b+c)+(a-b+d) = -a + b – c + a – b + d = d – c (a+b)-(-a+b-c) = a + b + a -b + c = a + 2c -(a+b)+(a+b+c) = -a -b + a + b + c = c Trả lời
-(a-b+c)+(a-b+d)
=-a+b-c+a-b+d
=d-c
(a+b)-(-a+b-c)
=a+b+a-b+c
=a+2c
-(a+b)+(a+b+c)
=-a-b+a+b+c
=c
-(a-b+c)+(a-b+d) = -a + b – c + a – b + d = d – c
(a+b)-(-a+b-c) = a + b + a -b + c = a + 2c
-(a+b)+(a+b+c) = -a -b + a + b + c = c
