Hint 1: Factorization
Remember that any quadratic expression can be rewritten as (x - p)(x - q). Try to spot factors quickly by checking the middle term multiplication!
Hint 2: The Quadratic Formula
When in doubt, use the quadratic formula:
x = (-b ± √(b²-4ac)) / 2a
Hint 3: Graphical Representation
Visualize the equation's graph – where it cuts the x-axis are the roots!
