JEE Main 24 June 2022, Shift 1, Maths Q27

Question 27 of 90 in this shift, Maths question 27 of 30, Section B.

Let max⁡0≤x≤2{9−x25−x}=α\max_{0\le x\le 2}\left\{\frac{9-x^2}{5-x}\right\}=\alpha and min⁡0≤x≤2{9−x25−x}=β\min_{0\le x\le 2}\left\{\frac{9-x^2}{5-x}\right\}=\beta. If ∫β−832α−1max⁡{9−x25−x,x}dx=α1+α2log⁡e(815)\int_{\beta-\frac{8}{3}}^{2\alpha-1}\max\left\{\frac{9-x^2}{5-x}, x\right\}dx=\alpha_1+\alpha_2\log_e\left(\frac{8}{15}\right) then α1+α2\alpha_1+\alpha_2 is equal to ______.
