Question

a + b square + a minus b square simplify this question​

Answer 1

(a+b)^2+(a-b)^2

(a+b)^2= a^2+2ab+b^2

(a-b)^2=a^2-2ab+b^2

hence,

a^2+2ab+b^2+a^2-2ab+b^2

2a^2+2b^2

Answer 2

(a+ b)^2 + (a- b)^2 = 2(a^2 + b^2) is the answer.

Step-by-step explanation:

• Given that, (a+b)^2 + (a-b)^2 .
• There are formula’s in algebra,  

1. (a+b)^2= a^2 + b^2 +2ab ,
2. (a-b)^2= a^2 + b^2 -2ab

• Therefore, (a+b)^2 + (a-b)^2 = a^2 + b^2 +2ab + a^2 + b^2 -2ab.
• Cancelling +2ab and -2ab we get, 2 a^2 + b^2.
• Hence, taking the 2 as common we get the solution, 2(a^2+b^2).
