Factor completely, then place the answer in the proper location on the grid. 9x 4 -225y^8
Nana76 [90]

Answer:

see explanation

Step-by-step explanation:

Given

9x^{4} - 225y^{8} ← factor out 9 from each term

= 9( x^{4} - 25y^{8} ) ← difference of squares

Difference of squares factors in general as

a² - b² = (a - b)(a + b)

x^{4} = (x² )² ⇒ a = x²

25y^{8} = (5y^{4} )² ⇒ b = 5y^{4}

Hence

x^{4} - 25y^{8}

= ( x^{4} -5y^{4} )( x^{4} + 5y^{4} )

Thus

9x^{4} - 225y^{8}

= 9 (x^{4} - 5y^{4} )( x^{4} + 5y^{4} )
