Find the x and y intercepts fast
In this video, I demonstrate how to quickly find the "x and y intercepts" of "quadratic equations" by inspection. We'll go ...
First we need to complete the square to get the coordinates of the turning point. \(y = {x^2} + 2x + 3\) \(y = {(x + 1)^2} - 1 + 3\) \(y = {(x + 1)^2} + 2\) Therefore ...
Now try the example questions below. Since -1 < 0, then it is a maximum turning point. \({b^2} - 4ac\) where \(a = - 1,\,b = 2\,and\,c = - 3\) \(= {2^2} - (4 \times ...
