completing the square turning point
How do you find the coordinates of a turning point?
The coordinates of the turning point and the equation of the line of symmetry can be found by writing the quadratic expression in completed square form. Find the equation of the line of symmetry and the coordinates of the turning point of the graph of \\ (y = x^2 - 6x + 4\\).
How do you complete a square if x2 is not 1?
Apply the following steps to “complete the square”. Observe the general form. If the coefficient of x2 is not 1, factorise the coefficient of x2 for the terms with x2 and x only. · b is represented by 4. **In general, b is always half the coefficient of the term with x (not x2). This is the “completed square”.
What is the technique of completing the square?
The technique of completing the square is a factoring technique that allows us to convert a given quadratic expression or equation in the form a x2 +b x +c to the form a ( x – h) 2 + k. We can use this technique to simplify the process of solving equations when we have complex quadratic equations.
How do you find a turning point in a quadratic graph?
Note: Since the graph is an inverted-U graph, the turning point is a maximum point and the coordinates are (− 5/2 , 35/2 ). In general, the coordinates of the turning point of a quadratic graph after completing the square, y = a (x + h)2 + k is always given by ( −h, k). This information is very useful for graph sketching.
