n is accurate) thatjl/P=3.44, the positive root, and MP=^—1.44, the negativeroot. For another example we require the roots of the follovjing equa-tion hy construction: y2+6y=27. N. B. When the numerals are too large in any equation forconvenience, we can always reduce them in the following… … CONIC SECTIONS. 41 to tlie left of the origin, is the center of the circle. We see bythe figure that 1 is the positive root, and —3 the negative root. But y=w5?, n=3, 2=1, y=3 or —9. We give one more example. Construct the equation Here c=4, and -^^=—6. Whence i2=2.2 Using the same figure as…
