Question

Factorize : \[x^4+ 3x^2+ 2\]

Answer 1

@Hero

Answer 2

Take \(u = x^2\).\[u^2 + 3u +2\]

Answer 3

Assume \(x^2=y\)
Then u will have
\(y^2+3y+2\)
Can u factorise this? @Glen_McGrath

Answer 4

Or you could just do\[x^4 + 3x^2 + 2 = x^4 + x^2 + 2x^2 + 2 = x^2(x^2 + 1) + 2(x^2 + 1) = (x^2 + 2)(x^2 +1)\]

Answer 5

Do you get it? @Glen_McGrath

Answer 6

GOOD parth It matches my answer key

Answer 7
