Questions & Step-by-Step Solutions

The sum of the roots of the equation x^2 - 7x + 10 = 0 is?
  • Step 1: Identify the coefficients in the quadratic equation x^2 - 7x + 10 = 0. Here, a = 1, b = -7, and c = 10.
  • Step 2: Use the formula for the sum of the roots of a quadratic equation, which is -b/a.
  • Step 3: Substitute the value of b into the formula. Since b = -7, we have -(-7)/1.
  • Step 4: Simplify the expression. This becomes 7/1.
  • Step 5: Calculate the result. 7/1 equals 7.
  • Step 6: Conclude that the sum of the roots is 7.
