Answer:
x^3+2x^2-4x+3y+z
Step-by-step explanation:
To find the answer we have to substract (x³ + 2x² -6x + 5) this from (-2x + 3y - z ) this
so ,
(x³ + 2x² -6x + 5)-(-2x + 3y - z )
=x^3+2x^2-6x+6+5+2x-3y+z
=x^3+2x^2-6x+2x+6+5-3y+z
=x^3+2x^2-4x+11+3y+z
=x^3+2x^2-4x+3y+z
(while subtracting we have to separate the like terms )
