I'm not sure if this is the right answer
Answer:
[tex]x^{4}[/tex] - 3x³ + 5
Step-by-step explanation:
Remove the parenthesis from the 2 expressions, that is
x² + 1 - 4x³ + 3[tex]x^{4}[/tex] - x² - 2[tex]x^{4}[/tex] + x³ + 4
Collect like terms, largest exponents to smallest, that is
(3[tex]x^{4}[/tex] - 2[tex]x^{4}[/tex]) + (- 4x³ + x³) + (x² - x²) + 1 + 4
= [tex]x^{4}[/tex] - 3x³ + 5 ← in standard form
