Completing The Square Method For Turning Point Of A Quadratic | Higher Maths

In this video we will use completing the square method to find the turning point and axis of symmetry of a quadratic equation. At Higher maths level, you need to be able to find the turning point of quadratics with negative coefficients of x squared and also with integer coeffecients.

0:00 - Discussion of completing the square method to find the turning point and axis of symmetry.

1:29 - Simple example of completing the square with the coefficient of x squared being 1.

2:43 - Example of completing the square method with an integer coefficient of x squared. Note the turning point is still given within the brackets at the end.

4:54 - Example of using the completing the square method to find the turning point when the coefficient of x squared is negative.

The next video will use completing the square and finding the roots to draw a sketch of a parabola.

Could you double check your last example please. A wee correction needed as the TP is at -1/4 on x. Thanks

Ur like the mr mwrrs history of math and helpful (mr Marr is also my teacher I’d recommend for ppl taking history at any level)
