Question

factorise it androots of m^3-1

Answer 1

m HAS THREE ROOTS 1 IS REAL AND 2 ARE COMPLEX ( IMAGINARY) ROOTS

m³- 1 = (m-1) (m²+m+1) =0

so m= 1 is first root,

m² + m + 1 = 0

two roots of m are possible from here by using descriminent....

first on left side is called 'w' and second is 'w²'
...... HERE w IS OMEGA....
