Given the coefficients [-5, 3, 14] and the degree 2, the polynomial is constructed as:
$$ - 5 x^{2} + 3 x + 14 $$
Step 2: Factor the Polynomial
To factor the polynomial, we look for factors that can divide the polynomial completely.
The factored form of the polynomial is:
$$ - \left(x - 2\right) \left(5 x + 7\right) $$
Final Answer:
The factored form of the given polynomial is: $$ - \left(x - 2\right) \left(5 x + 7\right) $$, rounded to 2 decimal places.
