Algebra,
We have,
a² + (1/a)² = 23
=> (a + 1/a)² - 2.a.1/a = 23 [Using the formula
a² + b² = (a + b)²- 2ab]
=> (a + 1/a)² - 2 = 23
=> (a + 1/a)² = 23 + 2
=> (a + 1/a)² = 25
so, (a + 1/a) = 5
Additional : Do you know who invented the branch of math 'Algebra' ?
you may know or not it is a Alkhwarizmi .
He is told to be the father of modern algebra.
That's it
Hope it helped (^o^)／
