Answer 2

Answer:

$x^{4}$ - 3x³ + 5

Step-by-step explanation:

Remove the parenthesis from the 2 expressions, that is

x² + 1 - 4x³ + 3$x^{4}$ - x² - 2$x^{4}$ + x³ + 4

Collect like terms, largest exponents to smallest, that is

(3$x^{4}$ - 2$x^{4}$) + (- 4x³ + x³) + (x² - x²) + 1 + 4

= $x^{4}$ - 3x³ + 5 ← in standard form
