Would really appreciate if someone with questions 3 and offering 13 points

Factor and solve to find roots x squared -x - 90 =0

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y > 2x + 3y is less than negative 3 over 2 times x minus 4part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points)part b: is the point (â’4, 6) included in the solution area for the system? justify your answer mathematically. (4 points)

What adds to be the bottom number but also multiplies to be the top number with 8 on the bottom and 15 on top
