RHS: ( (144u^2+140u)(u+1) = 144u^3 + 144u^2 + 140u^2 + 140u = 144u^3 + 284u^2 + 140u ).

Use ( x_0^2 + y_0^2 = 16 ): [ \left( \frac23(Y - 1) \right)^2 + \left( -\frac23(X + 2) \right)^2 = 16. ] [ \frac49 (Y - 1)^2 + \frac49 (X + 2)^2 = 16. ] Multiply by ( 9/4 ): [ (Y - 1)^2 + (X + 2)^2 = 36. ] Apotemi Yayinlari Analitik Geometri

Intersection with circle. Substitute ( y = m(x+2) ) into circle equation: [ (x+2)^2 + (m(x+2) - 1)^2 = 36. ] Let ( t = x+2 ). Then ( x = t-2 ). The equation becomes: [ t^2 + (m t - 1)^2 = 36 \implies t^2 + m^2 t^2 - 2m t + 1 = 36. ] [ (1+m^2)t^2 - 2m t + (1 - 36) = 0 \implies (1+m^2)t^2 - 2m t - 35 = 0. ] The roots ( t_1, t_2 ) correspond to ( x_1, x_2 ) of ( R_1, R_2 ). Their ( y )-coordinates: ( y_i = m t_i ). RHS: ( (144u^2+140u)(u+1) = 144u^3 + 144u^2 +

[ \text(a) (x+2)^2+(y-1)^2=36 \quad \text(b) Circle, center (-2,1),\ r=6 \quad \text(c) \inf \text area =0 \text as m\to 0^+ ] ] Multiply by ( 9/4 ): [ (Y - 1)^2 + (X + 2)^2 = 36

Discriminant: ( 72^2 - 4\cdot 37 \cdot 35 = 5184 - 5180 = 4 ). So ( u = \frac-72 \pm 274 ). Positive root: ( u = \frac-7074 ) (neg) or ( u = \frac-7474 = -1 ) (neg). No positive ( u )?

Expand LHS: ( 144u^3 + 288u^2 + 144u + 70u^2 + 140u + 70 = 144u^3 + (288+70)u^2 + (144+140)u + 70 ) ( = 144u^3 + 358u^2 + 284u + 70 ).
