(X^2 + 1 - 4x^3 + 3x^4) + (-x^2 - 2x^4 + x^3 + 4).
Express the answer in standard form. Enter your answer in the box.

- 3x³ + 5

Step-by-step explanation:

Remove the parenthesis from the 2 expressions, that is

x² + 1 - 4x³ + 3 - x² - 2 + x³ + 4

Collect like terms, largest exponents to smallest, that is

(3 - 2) + (- 4x³ + x³) + (x² - x²) + 1 + 4

= - 3x³ + 5 ← in standard form

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
