Solve the simultaneous equations: y - 3x + 2 = 0 y^2 - x - 6x^2 = 0

y = 3x -2(3x-2)2 - x - 6x2 = 0 9x2- 12x + 4 - x - 6x2 = 03x2 - 13x + 4 = 0(3x - 1)(x-4) = 0 x = 1/3 or x = 4then y = -1 when x = 1/3 and y = 10 for x = 4

How do I solve a cubic?


The curve y = 4x^2 + a/ x + 5 has a stationary point. Find the value of the positive constant a given that y-ordinate of the stationary point is 32.


A ball is projected at an angle b from the horizontal. With initial velocity V the ball leaves the ground at point O and hits the ground at point A. If Vcos(b) = 6u and Vsin(b) = 2.5u, how long does the ball take to travel between O and A.
