Question

3. (x³ + x² + x) – (4x³ + 2x – 3) + (2x³ – x² + 3x – 5)=? ​

Answer 1

Answer:

- x³+2x+2

Step-by-step explanation:

(x³ + x² + x) – (4x³ + 2x – 3) + (2x³ – x² + 3x – 5)

= x³ + x² + x – 4x³–  2x + 3 + 2x³ – x² + 3x – 5

= x³ + 2x³– 4x³   +   x² – x²   +   x + 3x –2x   +   3 – 5

= - x³+2x+2
