Question

Factorise: y4 + 4y2 - 32​

Answer 1

Answer:

it is y is the additional and variadial

Answer 2

Answer:

(y²+8)(y²+4)

Step-by-step explanation:

y⁴+4y²-32

By splitting middle term we need to find no.s p and q in such a way that pq= -32y⁴ and p+q= 4y²

So, 8y² and -4y² are such no.s

y⁴+8y²-4y²-32

y²(y²+8)-4(y²+8)

(y²-4)(y²+8)
