Hi if anyone can help me with this that would be greatly appreciated:) this is for math 30-1 polynomial functions, including remainder theorem, long division and division statement

The graph of a fourth degree polynomial function P(x) is shown below: . X - 10 5 10 -20 -40 P(x) -60 (0 , - 24 ) -80 100 -120 The polynomial function can be written as P(x) = a(x-b)?(x-c)(x+d), where a, b, c, and d are all positive integers. Find the values of a, b, c, and d. a= b= A/ C= A d=
