For the polynomial f(x) = -8x3 + 14x2 + 126x + 30, use the Rational Zeros Theorem to identify all possible rational zeros of the polynomial. Then find all actual zeros of the polynomial.
Enter your answer as a list of values separated by commas: Example: -4, 3, 2 Enter each value as a number (like 5, -3, 2.2172) or as a calculation (like 5/3, 2^3, 5+4) Enter DNE for Does Not Exist, oo for Infinity
