Answer:
7x^3 + 2x^2 - x
Explanation:
To subtract the two expressions (9x^3-4x^2+2x) and (2x^+6x^2-3x), we will need to line up the terms with the same exponent and subtract them.
(9x^3-4x^2+2x) - (2x^+6x^2-3x)
= (9x^3 - 2x^3) + (-4x^2 + 6x^2) + (2x - 3x)
= 7x^3 + 2x^2 - x
So the result of the subtraction is 7x^3 + 2x^2 - x
Please note that if you want to simplify the result further, you can combine like terms.
