Question

expand (a+2b- c)^2 this expression



​

Answer 1

• Answer:

(a+b+c)

(a+b+c) 2

(a+b+c) 2 =a

(a+b+c) 2 =a 2

(a+b+c) 2 =a 2 +b

(a+b+c) 2 =a 2 +b 2

(a+b+c) 2 =a 2 +b 2 +c

(a+b+c) 2 =a 2 +b 2 +c 2

(a+b+c) 2 =a 2 +b 2 +c 2 +2ab+2bc+2ca

• Step-by-step explanation:

Given,

Given,(a+2b+c)

Given,(a+2b+c) 2

Given,(a+2b+c) 2 =a

Given,(a+2b+c) 2 =a 2

Given,(a+2b+c) 2 =a 2 +(2b)

Given,(a+2b+c) 2 =a 2 +(2b) 2

Given,(a+2b+c) 2 =a 2 +(2b) 2 +c

Given,(a+2b+c) 2 =a 2 +(2b) 2 +c 2

Given,(a+2b+c) 2 =a 2 +(2b) 2 +c 2 +2a(2b)+2(2b)c+2ca

Given,(a+2b+c) 2 =a 2 +(2b) 2 +c 2 +2a(2b)+2(2b)c+2ca=a

Given,(a+2b+c) 2 =a 2 +(2b) 2 +c 2 +2a(2b)+2(2b)c+2ca=a 2

Given,(a+2b+c) 2 =a 2 +(2b) 2 +c 2 +2a(2b)+2(2b)c+2ca=a 2 +4b

Given,(a+2b+c) 2 =a 2 +(2b) 2 +c 2 +2a(2b)+2(2b)c+2ca=a 2 +4b 2

Given,(a+2b+c) 2 =a 2 +(2b) 2 +c 2 +2a(2b)+2(2b)c+2ca=a 2 +4b 2 +c

Given,(a+2b+c) 2 =a 2 +(2b) 2 +c 2 +2a(2b)+2(2b)c+2ca=a 2 +4b 2 +c 2

Given,(a+2b+c) 2 =a 2 +(2b) 2 +c 2 +2a(2b)+2(2b)c+2ca=a 2 +4b 2 +c 2 +4ab+4bc+2ac
