A The figure above shows the curve C with equation: R X y = 2x³ + 3x² - 11x - 6 The curve crosses the x-axis at the points P, Q and R(2,0). The tangent to C at R is the straight line L₁. The normal to C at P is the straight line L2. The straight lines L₁ and L2 meet at the point S. 3a) Find an equation of L₁. 3b) Show that LPSR = 90°.
