Question

Evaluate: (√5+√2)^2 - (√8-√3)^2

Answer 1

Hello mate !!!!!!!

Here is your answer....

(√5+√2)^2 - (√8-√3)^2

= {(√5)^2 + (√2)^2 +2×√5×√2} -

{(√8)^2+(√3)^2 - 2× √8×√3}

= (5 + 2 + 2√10) - ( 8 + 3 - 2√24)

= (7+2√10) - (11 - 4√6)

= 7 + 2√10 - 11 + 4√6

= - 4 +2√10 + 4√6

= 2(-2 +√10+ 2√6)
