Answer:
Factoring: a2b4c6-1
Ans - (ab²c³+1)*(ab²c³-1)
Step-by-step explanation:
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 1 is the square of 1
Check : a2 is the square of a1
Check : b4 is the square of b2
Check : c6 is the square of c3
Factorization is : (ab²c³ + 1) • (ab²c³ - 1)
