I NEED HELP PLEASE! A polynomial has zeros at -4 (multiplicity 3), -1 (multiplicity 8) and 2 (multiplicity 1). Which graph could represent this function?

There is a line with slope 1/a going through the point (a, a²). find the equation of the line perpendicular to this line at this point. (don’t let this problem intimidate you! solve the problem as you would if i’d given you specific values. just use variables instead.)

One line passes through (-7,-4) and (5,4) . another line passes through the point (-4,6) and (6,-9)

What are the solutions of the equation? 16x^2 + 24x + 5 = 5 a. 1/4, 5/4 b. -1/4, -5/4 c. -1/4, 5/4 d. 1/4 , -5/4
