Questions & Step-by-Step Solutions

If a polynomial is expressed as P(x) = 2x^3 - 4x^2 + 3x - 5, what is the coefficient of x^2?
  • Step 1: Identify the polynomial given in the question, which is P(x) = 2x^3 - 4x^2 + 3x - 5.
  • Step 2: Look for the term that contains x^2 in the polynomial.
  • Step 3: The term with x^2 is -4x^2.
  • Step 4: The coefficient is the number in front of x^2, which is -4.
  • Step 5: Therefore, the coefficient of x^2 in the polynomial P(x) is -4.
