Final answer:
The expression 3x² + 4x + 5 is a quadratic equation. It can be solved using the quadratic formula. Correct option is A. Quadratic
Step-by-step explanation:
The expression 3x² + 4x + 5 is a quadratic equation. A quadratic equation is a second-order polynomial with a variable squared (x²) as its highest degree term. In this case, the highest degree term is x², and the equation has a linear term (4x) and a constant term (5).
Quadratic equations can be solved using the quadratic formula: x = (-b ± √(b² - 4ac)) / (2a), where a, b, and c are the coefficients of the quadratic equation.
In this case, a = 3, b = 4, and c = 5. Substituting these values into the quadratic formula will give you the solutions to the equation.
