Curves \( a x^{2}+2 h x y+b y^{2}-2 g x-2 f y+c=0 \) and \( a^{\prime} x^{2}-2 h x y+ \) \( \left(a^{\prime}+a-b\right) y^{2}-2 g^{\prime} x-2 f^{\prime} y+c=0 \) intersect at four concylic points \( A, B, C \) and \( D \). If \( P \) is the point \( \left(\frac{g^{\prime}+g}{a^{\prime}+a}, \frac{f^{\prime}+f}{a^{\prime}+a}\right) \), thevalue of \( \frac{P A^{2}+P B^{2}+P C^{2}}{P D^{2}} \) ishttps://bit.ly/YTAI_PWAP https://www.pw.live
