Essential Formulas & Mathematical Definitions
Sum of zeros: α + β = -b/a
Product of zeros: α · β = c/a
Cubic: α+β+γ = -b/a, αβ+βγ+γα = c/a, αβγ = -d/a
Forming Quadratic Polynomials
A quadratic polynomial with roots α and β is given by P(x) = k[x² - (α + β)x + αβ].

High-Yield Exam Strategy & Scoring Tips
Step-by-Step Mark Allocation
Always state the governing principle or formula first, write given values with standard SI units, substitute clearly, and highlight the final numerical answer with units in a box for full step marking.
Common Calculation Traps
Watch for unit prefixes (cm to m, minutes to seconds, g to kg, degrees to radians). In coordinate and ray optics problems, double-check Cartesian sign conventions before computing.
