Solve the equations. 3(x+4)^2=10x+32
(x+4)^2=3x+40
(2x-3)(5x+1)=2x+2/5

Icould really use some with this question.

The american academy of pediatrics wants to conduct a survey of recently graduated family practitioners to assess why they did not choose pediatrics for their specialization. provide a definition of the population, suggest a sampling frame, and indicate the appropriate sampling unit.
