= 2x^3+8x^2-9x-5-3x^2+4x-6
= .....
take it from here
here is my answer 2x^3 5x^@-5x+1 is this right an swer.
Here is the answer I got
2x^3 5x^2-5x+1
2 x^3 + 5 x^2 - 5 x - 11
To simplify the expression (2x^3+8x^2-9x-5)-(3x^2-4x+6), you'll need to perform the subtraction operation.
First, distribute the negative sign to each term inside the parentheses of the second expression:
-(3x^2-4x+6) = -3x^2 + 4x - 6
Now rewrite the expression with the distribution:
(2x^3+8x^2-9x-5) - (3x^2-4x+6) = 2x^3 + 8x^2 - 9x - 5 - 3x^2 + 4x - 6
Next, collect like terms with the same exponent:
2x^3 + (8x^2 - 3x^2) + (-9x + 4x) - (5 + 6) = 2x^3 + 5x^2 - 5x - 11
Therefore, the simplified form of (2x^3+8x^2-9x-5)-(3x^2-4x+6) is 2x^3 + 5x^2 - 5x - 11.
