Question

Factor completely 3x^4 - 48

Answer 1

`3(x - 2) * (x + 2) * (x {}^(2) + 4`

Explanation:

`3x {}^(4) - 48`

Factor out 3 ⚂ from the expression

`3(x {}^(4) - 16)`

`using \: a {}^(2) - b {}^(2) = (a - b) \: (a + b)`

`3(x {}^(2) - 4) *(x {}^(2) + 4)`

`3(x - 2) * (x + 2) * (x {}^(2) + 4)`
