Question
Factor 
in the form 
. Then find the value of a, b and c.
Hint:
, where a and x can be real values, variables or multiples of both. We are asked to factorize the given expression in the form of and hence find the value of a, b and c.
The correct answer is: reduce time and space.
Step 1 of 3:
The given expression is 
. It can be written as, 
.
Step 2 of 3:
Substitute the values in the expression to get the factorized form;
Thus, the factorized form is: 
Step 3 of 3:
The factorized form is .Comparing it with , the values of a, b and c are:
Thus, the factorized form is:
Step 3 of 3:
The factorized form is
.Comparing it with , the values of a, b and c are:We use polynomial identities to factorize and expand polynomials to reduce time and space.
