1.these are of many types but we are concerned with quadratic and cubic mainly. 2.for :ax^2 +bx+c=0,to solve these questions some points to remember: a)the given eqn has MAX 2 distinct roots(real or imaginary)depending upon D. b)find D(discriminant) ie D=b^2-4ac NOW if D=0 both roots are real and equal if D>0 both roots are real but distinct if D<0 then both roots are imaginary(NOTE:Imaginary roots are in conjugate form if if one root is 2+3i,then other must be 2-3i) NOW if inequation is given in the form of ax^2+bx+c> OR<0 then how can WE SOLVE soln: 1.Make the sign of "a" POSITIVE in above equation(if already a is positive then it's ok ELSE multiply the above equation by -1 and change the inequality sign as well) NOTE:in 99 % of inequality questions we can always make the factors of the inequation and put in the form of (x-X)(x-Y)>or<0 AS THE CASE MAY BE.(suppose X0 it means our answer lies in POSITIVE sections of the no. line ie x belongs to(-infinity,X) UNION (Y,infinity) if (x-X)(x-Y)<0 then answer is x belongs to(X,Y) NOW we will know about the bature of parabola opening upwards or downwards and find MAX or MIN value thereof.
