  • you search the roots of equation given x^2 = X so X^2 -8X +15 =0 you have X =5 and X=3 this yields for x1 = sqrt5 x2 = -sqrt5 x3 = sqrt3 x4 =-sqrt3 and the result is (x-sqrt5)(x+sqrt5)(x-sqrt3)(x+sqrt3) you put -2q^2 in factor …

  • put cos x =y you find 2y^2 -y =0 y (2y-1) =0 two answers y= 0 y =+0.5 translating in angles y = (2k+1) 90° k = integer or y = 60° + 2kpi
