12. The golden ratio is a famous number/ratio in mathematics that can be traced back to the work of Euclid. This ratio is known for being aesthetically pleasing and can be found in all kinds of mathematical objects, art, and literature. The golden ratio occurs when the ratio between two values (a and b) is equal to the ratio of a+b to a. Thus, this relationship can be modeled by the equation a+b 4 = = - where qp is the value of the golden ratio. Determine the exact value of q. a
