Provide an appropriate response.Use the equation 2x2 + 5x = c to explain how to solve a quadratic equation by completing the square.
What will be an ideal response?
Divide both sides of the equation by 2. Add 
to both sides of the equation. Take the square root of both sides of the equation, being careful to remember to use the positive and negative square roots of the right side. Then add - 
to both sides of the equation.
