Express the answer in standard form. Enter your answer in the box.

Answer 1

X⁴-3x+1

X²+1-4x⁴-x²+³

X²+1-3x²+x⁴-x²

1-3x²+x⁴

X⁴-3x³+1

I'm not sure if this is the right answer

Answer 2

`x^(4)` - 3x³ + 5

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
