Textbook Problem

To find the golden ratio (see the Discover activity on page 227), solve the equation 1 L = L − 1 L for L.(HINT: You will need the Quadratic Formula.) To determine

To find:

The solution of L.

Explanation

According to the quadratic formula, the solutions of ax2 + bx + c = 0 are given by

x=b+b24ac2a,bb24ac2a

Calculation:

Consider, 1L=L11

L(L1)=11L2L=1L2L1=0

Use the quadratic formula in L2L1=0
