    1. Best Answer

      x² – 3x – 10 = 0
      solving the quadratic equations, we got
      x² – 3x – 10 = 0
      ⇒ x² – 5x + 2x + 10 = 0
      ⇒ x(x -5) + 2x (x – 5) = 0
      ⇒ (x – 5) (x + 2) = 0
      ⇒ (x – 5) = 0 or (x + 2) = 0
      Either x = 5 or x = -2
      Hence, the roots the given quadratic equations are 5 and -2
