Answer: 9 (x^2 -5y^4) (x^2+5^4)
Step-by-step explanation:
Hi, to solve this we have to analyze the equation.
9x^4 -225 y ^8
First, we have to remove the common factor (9)
So, mathematically speaking:
9 (x^4 -25y^8)
The next step is to factor the difference of two perfect squares
9 (x^2 -5y^4) (x^2+5^4)
