Answer 2

Answer:

96(y+3)(y-3)

Step-by-step explanation:

48(2y⁴-36y²+162)

= 48×2(y⁴-18y²+81)

= 96[(y²)²-2×y²×9+9²]

= 96(y²-9)²

/* By algebraic identity:

a²-2ab+b² = (a-b)² */

= 96(y²-3²)

= 96(y+3)(y-3)

/* By algebraic identity:

a²-b² = (a+b)(a-b) */

Therefore,

48(2y⁴-36y²+162)

=96(y+3)(y-3)
