Question

simplify:(x + 5)^2 + (x – 3)^2​

Answer 1

Answer :

2x² + 4x + 34

Formulae applied :

• (a + b)² = a² + b² + 2ab

• (a - b)² = a² + b² - 2ab

Explanation :

(x + 5)² + (x - 3)²

x² + 25 + 10x + x² + 9 -6x

2x² + 4x + 34

Answer 2

(x + 5)2 + ( x -3)2

x2 + 25 + 10x + x2 + 9 - 6x ( using identity (a+b)2 = a2 + b2 + 2ab)

2x2 + 34 - 4x

hope it's help ✌✌
