To solve this problem, you just need to distribute the negative sign to every term inside the brackets, and then combine like terms.
So,
(5x^2 + x - 3) - (-2x^3 + 4)
= 5x^2 + x - 3 + 2x^3 - 4
= 2x^3 + 5x^2 + x - 7
Therefore, the answer is option A, -2x^3 + 5x^2 + x - 7.
Question 6.
(5x^2 + x - 3) - (-2x^3 + 4)
A. -2x^3 + 5x^2 + x - 7
B. 2x^3 + 5x^2 + x + 1
C. 2x^3 + 5x^2 + x - 7
D. 2x^3 + 5x^2 + x + 1
