Factorise using Factor Theorm
Asked by ArunimaJ95 | 14th Dec, 2009, 09:51: AM
take factors of the number term i.e. the term without the variable
the factors are
assuming the given polynomial as p(x) and each of these numbers as a turn by turn, find p(a).
aways start with the smalest number.
so p(-1), p(1) etc
the number a at which you get p(a)=0
tells you that x-a is a factor.
divide by the factor , then you will get a poly of one degree ower, in this case, tou will get a cubic poly. apply the same method, you will gat another factor and a quadratic poly. factorise the quad poly by the usual method.
this gives you all thefactors.
