Answer:
(9+8x)(9-8x)
Step-by-step explanation:
We have to factorize the term 81-64x².
Now, we know that factorization is a mathematical process by which a mathematical expression is represented by the product of two or more different mathematical terms.
Hence, 81-64x²
=(9)²- (8x)² {Here we will use the formula (a²-b²)= (a+b)(a-b)}
=(9+8x)(9-8x) (Answer)
Therefore, this is the required factorization and the two factors are (9+8x) and (9-8x).
