Question
Use polynomial identities to factor the polynomials or simplify the expressions : x9 - 8
Hint:
, here a and b can be real values, variables or multiples of both. We are asked to use polynomial identities to factorize the given expression.
The correct answer is: x9 - 8 = (x3 - 2)(x6 + 2x3 + 4)
Step 1 of 2:
The given expression is x9 - 8 . We can rewrite it as, 
. It is of the form 
. Here, 
.
Step 2 of 2:
Use the polynomial identity to simplify the expression;
Thus, the simplified expression is; 
.
Thus, the simplified expression is;
.Polynomial identities are used to reduce the time and space while you solve higher degree polynomial expressions
