Question

add x^3+5x^2+3x to 6x^2-8x^3+8​

Answer 1

Answer:

-7x³ + 11x² + 3x + 8

Step-by-step explanation:

First writing the equation :

(x³ + 5x² + 3x ) + (6x² - 8x³ + 8)

(x³ + 5x² + 3x ) + (6x² - 8x³ + 8)= x³ + 5x² + 3x + 6x² - 8x³ + 8

on rearranging

= x³ - 8x³ + 5x² + 6x² + 3x + 8

= -7x³ + 11x² + 3x + 8
