We learn how to find the equation of a parabola when it only has one zero, that’s one x-intercept. We use root factoring to root factor the quadratic’s equation and the use the coordinates of one other point the parabola passes through to find its equ...

We learn how to write a number as a logarithm to simplify expressions in which a number is being added to, or subtracted from, a logarithm. Any number can be written as a logarithm in any chosen base. We learn the method for doing this with some detailed...
