Question

( x²-1)²+8x( x²+1)+19x² ( solve) ​

Answer 1

Step-by-step explanation:

( x²-1)²+8x( x²+1)+19x²

x⁴+1-2x²+8x³+8x+19x²

x⁴+8x³+17x²+8x+1

Answer 2

${( {x}^{2} - 1) }^{2} + 8x( {x}^{2} + 1) + 19 {x}^{2}$

$= {x}^{4} - 2 {x}^{2} - 1 + 8 {x}^{3} + 8x + 19 {x}^{2}$

$= {x}^{4} + 8 {x}^{3} + 17 {x}^{2} + 8x - 1$
