Polynomials

We are given the cubic equation . To find the roots, we can start by checking possible integer roots using the Rational Root Theorem. The possible rational roots are the factors of the constant term (30) divided by the factors of the leading coefficient (1), which are: . Step 1: Check
Substitute into the equation: Thus, is a root. Step 2: Check
Substitute into the equation: Thus, is also a root. Final Answer:
