Wavy curve method in about 5 minutes for solving polynomial inequalities

Inequalities: Logic behind wavy curve method

Solved example 1 : Wavy curve method x^3 is less than or equal to 4x

Solved example 2 : Wavy curve method (x^2-3x+2)(x^2-x-1)(5-x) is less than 0

Synthetic division of polynomials : Linear and Quadratic factors (binomial and trinomial divisors)

Logic behind : Synthetic division of polynomials

Synthetic division when leading coefficient of linear divisor is not 1

Learn to solve Cubic inequalities using wavy curve method in 4 minutes [Polynomial inequalities]

Quadratic inequalities Always positive/ negative condition (Very Important) for JEE and K12.
