Question 1109753: A A point p divides a straight line ab in the golden ratio if AB:AP =AP:PB. Draw a diagram letting AB=x an AP =1 and form a quadratic equation for the Golden Ratio, x. Show that solution is x=(sqrt(5)+1)/2.
I'm very confused

Draw the picture!

If AB=x and AP=1, then PB = 1-x.

Put those measurements in the given proportion
AB%2FAP+=+AP%2FPB
and solve the proportion.
