The difference between the polynomial is [tex]\rm 9x^3-5x^2-6x+10[/tex].
The subtract means to take away from a group or a number of things.
Lorne subtracted 6x3 – 2x + 3 from –3x3 + 5x2 + 4x – 7.
The difference between the expression is;
[tex]\rm ( 6x^3 - 2x + 3 )- (-3x^3 + 5x^2 + 4x - 7)[/tex]
[tex]\rm 6x^3 - 2x + 3 +3x^3 -5x^2 -4x +7\\\\9x^3-5x^2-6x+10[/tex]
Hence, the difference between the polynomial is [tex]\rm 9x^3-5x^2-6x+10[/tex].
