Question

7. Factorize x4 – 3x² + 2.

step by step explanation​

Answer 1

Step-by-step explanation:

$x(1) = {1}^{4} - 3 ({1}^{2} ) + 2 \\ = 1 - 3 + 2 \\ = - 2 + 2 = 0$

$x( - 1) = { - 1}^{4} - 3( { - 1}^{2} ) + 2 \\ = 1 - 3 + 2 \\ = - 2 + 2 = 0$

On dividing with x² -1

we get , x² -2

.= x²-2 × x² -1
