The expression can be rewritten as, by taking the common factor, 9 x³y³(2x - 4y), so option C is correct.
Common factors are those that apply to two or more different integers. To put it another way, a common factor is a number that will divide a group of two numbers exactly.
Given:
18 x⁴y³− 36x³y⁴
Factorize the above expression,
9 × 2 x⁴y³ - 9 × 4x³y⁴
Take common 9 x³y³
9 x³y³(2x - 4y)
Therefore, the expression can be rewritten as, by taking the common factor, 9 x³y³(2x - 4y).
