ii.

The rate of oxygen consumption in a bioreactor, G(t)G(t)G(t), is modeled by the function G(t)=2t3−7t2−12t+52(t−3)2G(t) = \frac{2t^3 - 7t^2 - 12t + 52}{(t - 3)^2}G(t)=(t−3)22t3−7t2−12t+52​ for t>3t > 3t>3.

Given that G(t)=At+B+C(t−3)2G(t) = At + B + \frac{C}{(t - 3)^2}G(t)=At+B+(t−3)2C​ where AAA, BBB and CCC are constants to be found, find
