Question

( - 6x^3 + 5x - 3 ) - ( 2x^3 + 4x^2 - 3x + 1)

Answer 1

To subtract both polinomials you have to perform the operations only between the like terms:

`-6x^3+5x-3`

minus

`2x^3+4x^2-3x+1`

The first equation doesn't have a "x²" term so I'll write 0x² to complete the equation:

The result is -8x³ -4x² +8x -7
