Next, one (the number) times something is just the something, there is no reason to continue to write the one. For instance, Do not write this as ! The coefficient Hey , please verify your email address. If we had the equation t(t - 6) = 0 it would be true that t = 0 or t - 6 = 0. We illustrate the use of the quadratic formula with a third example.

Note also that the derivative of $\ln(x^2-2x+2)$ is $$\frac{2x-2}{x^2-2x+2}.\tag{1}$$ The derivative is $0$ precisely if $2x-2=0$, that is, if $x=1$. Once I completed this, I was then asked to find and classify the stationary point I usually use quadratic formulas to start this off, but for some reason I'm receiving a We follow this definition: $$f'(x)=\frac{2x-2}{x^2-2x+2}=0\implies x=1$$ Now, let's take the 2nd-order derivative: $$\frac{d^2f(x)}{dx^2}=\frac{df'(x)}{dx}=f''(x)=[\ln(x^2-2x+2)]''=(\frac{2x-2}{x^2-2x+2})'=\frac{2x(2-x)}{({x^2-2x+2})^2}$$ Meaning: the rate-of-change of the rate-of-change (Think of it as measure of how much the function is curving, Remember, is not defined in the real numbers -- no wonder your calculator is pitching a fit!
