This is vector calculus

Find the (x, y, z) coordinates of the points P where the line I(t) = (x (t) , y (t) , z (t) ) = (2 + 3t, 1 - t, 1 + 2t) intersects the sphere x2 + y + z2 = 6. If there is more than one such point P, give your answers as a comma-seperated list. If there is no such point, enter DNE. ( x, y, Z) =
