Answer

Final Answer: The polynomial of degree 3 that has the given zeros -5, 5, and 7 is \(\boxed{P(x) = x^3 - 7x^2 - 25x + 175}\).

Steps

Step 1 :We are given that the polynomial is of degree 3 and has zeros -5, 5, and 7.

Step 2 :A polynomial of degree 3 with zeros -5, 5, and 7 can be written in the form of \(P(x) = a*(x - r1)*(x - r2)*(x - r3)\), where \(r1 = -5\), \(r2 = 5\), and \(r3 = 7\).

Step 3 :The constant a can be any non-zero number, but for simplicity, we can choose \(a = 1\).

Step 4 :Substituting the values of a, r1, r2, and r3 into the equation, we get \(P(x) = x^3 - 7x^2 - 25x + 175\).

Step 5 :Final Answer: The polynomial of degree 3 that has the given zeros -5, 5, and 7 is \(\boxed{P(x) = x^3 - 7x^2 - 25x + 175}\).
