wavy curve method is used to find the solution of inequalities
so plot all the points on the real line . Put a value ( large positive number) and put the sign accordingly and then simply change the sign or remain it same as u pass through other points depending on whether the function is even or odd , if it's even the sign remains same and for odd it changes .

because there is odd power of x-2 and x-3 so the sign will change as we will go pass through them
