Question

simplify :-(√3+√11) ^2 + (√3 -√11) ^2​

Answer 1

(√3+√11) ^2 + (√3 -√11) ^2
= [(√3)^2 + (√11)^2 + 2(√3)(√11)] + [(√3)^2 + (√11)^2 - 2(√3)(√11)]
= [3 + 11 + 2(√3)(√11)] + [3 + 11 - 2(√3)(√11)]
= 14 + 2(√3)(√11) + 14 - 2(√3)(√11)
= 28 (Answer)

Answer 2

Step-by-step explanation:

(√3+√11)^2 + (√3-√11)^2

=[(√3)^2+(√11)^2 + 2(√3) (√11)]+ [√3)^2+(√11)^2-2(√3)(√11)]

[3+11+2(√3)(√11)] + [3+11-2(√3) (√11)]

14+2(√3)(√11)+14-2(√3)(√11)

28 (your answer)
