Formulae
Zeroes of quadratic :-
1. In general form of quadratic polynomial, p(x) = ax² + bx + c
2. Sum of its zeroes (α + β) = -b/a = (- coefficient of x)/(coefficient of x²)
3. Product of zeroes (αβ) = c/a = (constant term)/(coefficient of x²)
    
Zeroes of Cubic :-
1. In general form of cubic polynomial, p(x) = ax³ + bx² + cx + d
2. α + β + γ = -b/a
3. αβ + βγ + γα = c/a
4. αβγ = -d/a
    
Division :-
1. Dividend = (Divisor × Quotient) + Remainder
2. p(x) = g(x)q(x) + r(x)
