Ex. 3. The conicoids ■2z^ - 2>/z - 5zx - Gx>/ + z = 0, 4z^ - 6>/z - \Ozx + Ixj/ + 2z = have four common generators.
(y = 0, z = ; 2 = 0, x=0 ; x=0, ^i/-2z = l ; ?/ = 0, 5. R-22 = l. ) Ex. 4. The conicoids z^ + di/z + 6zx - Zxy - 1 2? = 0, 4j2 - 2?/2 - Azx + 2. Iv/ + 82 = have two conimon generators and touch at all points of these generators.
Ex. 5. Prove that the intersection of tlie coniccnds 22 + 22-. Y + 2=0, y'^-'2ij-x-\=^ is a quartic curve whose equations may be written . V=A*-2, ...v/ = A2+l, 2 = A-1.
Ex. 6. Find the points of intersection of the plane A" -9;/- 42 = and the quartic curve which is common to the parabolic cylinders 22 + 102-y + 26 = 0, /-2j/-, r + 2 = U. Am. Two coincident at (17, 5, -7) ; (2, 2, -4) ; (82, 10, -2). Ex. 7.
