Step 1
A polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Factoring polynomials involves breaking up a polynomial into simpler terms (the factors) such that when the terms are multiplied together they equal the original polynomial.
Step 2
The given polynomial is 36a212a+1. Factor the polynomial completely by simplifying and taking the common terms out as follows;
36a212a+1=36a26a6a+1
=6a(6a-1)-1(6a-1)...Take the common terms out.
=(6a1)2....Factored form.
Hence, the given polynomial is factored completely and is equal to 36a212a+1=(6a1)2.

Given expression: 36a212a+1
Factor this expression completely.
View the expression 36a212a+1 as
36a212a+1uct 361=36
Find two integers such that whose product is 36 and whose sum is -12.
Since -6*-6=36, (-6)+(-6)=-12, the two integers are -6,-6.
So the middle term -12a can be written as -12a=-6a-6a.
Then, factor 36a26a6a+1
=36a26agroup6a+1group
=6a(6a1)group1(6a1)group(Facr out GCF om each group)
=(6a-1)(6a-1) (Factor out (6a-1) from each group)
Therefore, 36a212a+1=(6a1)(6a1)
Check:
Considering,
(6a-1)(6a-1)=6a(6a-1)-1(6a-1)(using distributive property)
=36a26a6a+1 (using distributive property)
=36a212a+1 (combine like terms)
Therefore, 36a212a+1=(6a1)(6a1) or =(6a1)2
