The answer is 1 + √2
sqrt(2) is

sqrt(3 + 2 sqrt 2) is

Now, let's simplify

.
We will use square of sum: (a + b)² = a² + 2ab + b²
Answer: according to spark notes: There can be 0, 1, or 2 solutions to a quadratic equation, depending on whether the expression inside the square root sign, (b2 - 4ac), is positive, negative, or zero. This expression has a special name: the discriminant.
In this case it is 0, not 2, which was my first and wrong answer
you multiply the number of years
