The graph of \(y = x^2 - 6x + 9 \) touches the x-axis at \( x = 3\). It is not possible to find the square root of a negative number, so the equation has no solutions. The graph of \(y = x^2 + 2x ...

You can use the same formula in Excel, Excel Online, and Google Sheets to calculate the cube root or cube of any number or value. There is no specific known function for finding the cube or cube ...

Writing \(y = x^2 – 6x + 4 \) in completed square form gives \(y = (x – 3)^2 – 5\) Squaring positive or negative numbers always gives a positive value. The lowest value given by a squared ...
