Answer 2

The simplified form of the given expression is 2(a² + b).

The given expression is

(a + b)² + (a – b)²

Using algebraic formulas:

(a + b)² + (a – b)² = (a² + 2ab + b²) + = (a² – 2ab + b²)

Combine like terms.

(a + b)² + (a b)² = (a² + a²) + (2ab 2ab) + (b² + b²)

(a + b)² + (a - b)² = 2a² +0+ 26²

(a + b)² + (a – b)² = 2a² + 26²

(a + b)² + (a - b)² = 2(a² + b²)

Therefore the simplified form of the given expression is 2(a² + b²).
