Trying to factor as a Difference of Squares:
2.1 Factoring: 9x-1
Theory : A difference of two perfect squares, A - B can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A - AB + BA - B2 =
A
- AB + AB - B2 =
A - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 9 is the square of 3
Check : 1 is the square of 1
Check : x is the square of x1
Factorization is : (3x + 1) • (3x - 1)
Final result :
(3x + 1) • (3x - 1)
