Question

(a+b)^2 +(a-b)^2 simplify the given equation

Answer 1

Answer:

Step-by-step explanation:

a^2 + 2ab + b^2 + a^2 -2ab +b^2 (based on formula)

2a^2 + 2b^2

2 (a^2+b^2)

2 (a+b)(a-b)

Answer 2

${(a + b)}^{2} + (a - b)^{2} \\ = {a}^{2} + {b }^{2} + 2ab + {a}^{2} + {b}^{2} - 2ab \\ = 2 {a}^{2} + 2 {b}^{2} \\ = 2( {a}^{2} + {b}^{2} )$

and also you can put the value of :

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