4 Students are discussing about the ‘completing square’ method when solving a quadratic equation. Who is making a correct statement?
1
John: This method will only work when the roots are whole numbers.
2
Nancy: This method will only result in roots which are real.
3
Timothy: There is no need to bring the constant term to the right hand side in the first step.
4
Jane:The coefficient of x2
must be 1 before we can complete the square.

(05.03 mc) part a: explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x−2 intersect are the solutions of the equation 4x = 2x−2. (4 points) part b: make tables to find the solution to 4x = 2x−2. take the integer values of x between −3 and 3. (4 points) part c: how can you solve the equation 4x = 2x−2 graphically? (2 points)
