Quick Math Hack: Plug In Values the Right Way (With Positives & Negatives!)

Math hack alert! This quick, fun example shows how to evaluate expressions like 4x² - 3x + 1 when x = -2. We walk step-by-step through plugging it in, breaking it down, and keeping signs straight!

After you replace the x's, it's time for order of operations. For this example: exponents, multiply, add and subtract from left to right.

Whether you're reviewing for Algebra 1 or just trying to understand how negatives and exponents work together, this video’s for you.
