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

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

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

Difference of squares factors in general as

a² - b² = (a - b)(a + b)

$x^{4}$ = (x² )² ⇒ a = x²

25 $y^{8}$ = (5 $y^{4}$ )² ⇒ b = 5 $y^{4}$

Hence

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

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

Thus

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

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