Compute {{MATH_84}} and {{MATH_85}}, {{ENV_86}} On the other hand {{ENV_87}} The critical points are where {{MATH_88}}, thus we need to solve {{MATH_89}} for {{MATH_90}}. This equation has two solutions. If we call them {{MATH_91}} and {{MATH_92}}, with {{MATH_93}}, then what are {{MATH_94}} and {{MATH_95}}? {{MATH_96}}
