Question

Determine the solutions of the quadratic equation by inspecting the graph. Give answers correct to 1 decimal place where appropriate.

  1. x = -5, 5
  2. x = -3, 3
  3. x = -4, 4
  4. x= -2, 2

The correct answer is: x = -5, 5


    The graph touches the x-axis at x = - 5, and x = 5, so the solutions of the quadratic equation are x = -5 and x = 5.
