To find the difference of the two polynomials, we need to distribute the negative sign to every term in the second polynomial:
(6x^3 - 2x^2 + 4) - (-2x^3 - 4x^2 + 5)
Simplifying,
6x^3 - 2x^2 + 4 + 2x^3 + 4x^2 - 5
Grouping like terms,
(6x^3 + 2x^3) + (-2x^2 + 4x^2) + (4 - 5)
Combining like terms,
8x^3 + 2x^2 - 1
So, the difference of the two polynomials is 8x^3 + 2x^2 - 1.
whats the difference of the following polynomials?
(6x^3-2x^2+4)
-(2x^3+4x^2-5)
