Alright, future engineers!
**Absolute Value:** The distance of a number from zero, always positive.
Ex: `| -7 | = 7`.
Pro-Tip: When solving `|x|=a`, remember `x=a` OR `x=-a`! Essential for error analysis & tolerances.

**Quadratic Eq:** An equation where the highest exponent of the variable is 2.
Ex: `ax^2 + bx + c = 0`.
Pro-Tip: Its solutions (roots) show where the parabola crosses the x-axis! Essential for optimizing & modeling arcs.

Alright, future engineers!
**Absolute Value:** The distance of a number from zero on the number line, always non-negative.
Ex: `| -7 | = 7` & `| 7 | = 7`.
Pro-Tip: Always think of it as distance, so the result is NEVER negative! Essential for error margins & magnitude.
