Simplify k² − 10k + 6 = 0

Here are the solutions to the remaining questions:

8. Simplify $k^2 - 10k + 6 = 0$
This is a quadratic equation. To "simplify" an equation means to solve for the variable $k$. We will use the quadratic formula $k = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$.
For the equation $k^2 - 10k + 6 = 0$, we have $a=1$, $b=-10$, and $c=6$.

Step 1: Substitute the values of $a$, $b$, and $c$ into the quadratic formula.
