To factorise z 3 1 into a linear and quadratic factor, it is best to try the factor theorem first We set the equation to zero z 3 1=0We need to find a value of z such that the above is true By inspection we can see that if z=1 then the above is true because (1) 3 1=0 since (1) 3 =1Therefore, (z1) is a factor The other factor is quadraticHere, the exponent of the second term, ie, x–1 is –1, which is not a whole number So, this algebraic expression is not a polynomial Again, x 3 can be written as 1 2 x 3 Here the exponent of x is 1 2, which is Supritha, added an answer, on 3/10/15 Supritha answered this It is form of (a)^ 3 (b)^ 3 (c)^3 =3abc where abc=0 a=xy , b=yz , c=zx abc= 0 = (xy) (yz) (zx)=0 = xyyzzx=0 = 0 =0 (a)^ 3 (b)^ 3 (c)^=3abc
