    Alright, future engineers!
    **Quadratic Formula:** Finds roots (x-intercepts) for any `ax^2 + bx + c = 0`.
    Ex: `x = [-b +- sqrt(b^2 - 4ac)] / 2a`
    Pro-Tip: The `b^2-4ac` (discriminant) tells you if roots are real/complex, & how many!

    Alright, future engineers!

    **Difference of Squares:** A binomial `a² - b²` that factors into `(a - b)(a + b)`.
    Ex: `x² - 9 = (x - 3)(x + 3)`
    Pro-Tip: Spot this pattern to quickly simplify expressions & solve equations! Saves tons of time.
