Questions & Step-by-Step Solutions

What is the product of the roots of the equation x^2 + 3x - 10 = 0?
Correct Answer: -10
  • Step 1: Identify the equation given, which is x^2 + 3x - 10 = 0.
  • Step 2: Recognize that this is a quadratic equation in the form ax^2 + bx + c = 0.
  • Step 3: Identify the values of a, b, and c from the equation: a = 1, b = 3, c = -10.
  • Step 4: Use the formula for the product of the roots of a quadratic equation, which is given by c/a.
  • Step 5: Substitute the values of c and a into the formula: c/a = -10/1.
  • Step 6: Calculate the result: -10/1 = -10.
  • Step 7: Conclude that the product of the roots of the equation is -10.
