Find an equation of the line perpendicular to the graph of 28x-7y=9 that passes through the point at (4,1)

What is the solution to the equation below? 3/x-2+6=square root x-2 +8

Answer asap! show all work! find the number of complex roots, the possible number of real roots and the possible rational roots of the polynomial function. then, solve for all roots. x^3 + 2x^2 + 3x + 6 = 0
