Question

4xpower3-2xpower2+5x-1+8x+xpower2-6power 3+7-6x+3xpower2-xpower3​

Answer 1

Answer:

$4x^3 - 2x^2 + 5x - 1 + 8x + x^2 - 6^3 + 7 - 6x + 3x^2 - x^3$ $=3x^3 + 2x^2 + 7x - 210$

Step-by-step explanation:

$4x^3 - 2x^2 + 5x - 1 + 8x + x^2 - 6^3 + 7 - 6x + 3x^2 - x^3$

$=4x^3 - x^3 - 2x^2 + x^2 + 3x^2 + 5x + 8x - 6x - 6^3 + 7 - 1$

$=3x^3 + 2x^2 + 7x - 216 + 7 - 1$

$=3x^3 + 2x^2 + 7x - 210$
