P.o.t.W. #9 Solution
gradient of line, \(m = \frac{{a{c^2} - a{b^2}}}{{c - b}} = \frac{{a\left( {c + b} \right)\left( {c - b} \right)}}{{c - b}} = ac + ab equation of line: \(y - a{b^2} = \left( {ac + ab} \right)\left( {x - b} \right) \(y = \left( {ac + ab} \right)x - abc - a{b^2} + a{b^2} \(y = \left( {ac + ab} \right)x - abc area of bounded region...
