1.	Let t1,t2,t3 be three points on the parabola y2=4x. If the normal at t1 intersects the parabola at t2 and the normal at t2 intersects the parabola at t3 such that 3t1+13t2+9t3=0, then
Answer» Let $t_{1}, t_{2}, t_{3}$ be three points on the parabola $y^{2} = 4 x$ . If the normal at $t_{1}$ intersects the parabola at $t_{2}$ and the normal at $t_{2}$ intersects the parabola at $t_{3}$ such that $3 t_{1} + 13 t_{2} + 9 t_{3} = 0$ , then
