(B) 0

(C) 1+2√2

(D) 1

ANSWER : A

I NEED EXPLANATION. DONT DEFINE THE GOLDEN NUMBER JUST ANSWER IF U KNOW.

Answer 1

HEYA...

Answr...

The Golden Ratio has unique mathematical properties. It is the only positive number whose square is one greater than itself. It is the only positive number whose reciprocal is one less than itself. It is also the found in limits and the Fibonacci series. These properties make it the unique solution to optimize design, in practicality and in beauty


Now we have a formula that can be solved using thequadratic formula. This formula allows you to solve a quadratic equation for an unknown x, with a, b, and c as constants. A quadratic equation has this form:

ax² + bx + c = 0

The solution to this is found with the quadratic formula:

So our formula for the golden ratio above (B2 – B1 – B0 = 0) can be expressed as this:

1a2 – 1b1 – 1c = 0

The solution to this equation using the quadratic formula is (1 plus or minus the square root of 5) divided by 2:

(  1 +  √5 ) / 2 = 1.6180339… = Φ

(  1 –  √5 ) / 2 = -0.6180339… = -Φ

The reciprocal of Phi (denoted with an upper case P), is known often as by phi (spelled with a lower case p).


RESULT...

Phi, Φ, 1.618…, has two properties that make it unique among all numbers. 


From ur above options

(  1 +  √5 ) / 2
is the right answr....

hope its helpful...
