Simplify (5x3− x + 14) − (3x2− 9x + 4). a) 5x3− 3x2+ 8x + 10 b) 2x2+ 8x + 10 c) 5x3− 3x2− 10x + 18 d) 2x2− 10x + 18

The correct answer option is A) 5x^3-3x^2+8x+10.

Step-by-step explanation:

We are given the following expression and we are to simplify it:

To simplify this expression, we will open the brackets and arrange the like terms together to get:

= 5x^3 - x + 14 - 3x^2 + 9x-4

= 5x^3 - 3x^2 - x + 9x + 14 - 4

= 5x^3 - 3x^2 + 8x + 10

Therefore, the correct answer option after simplifying the given expression is A) 5x^3-3x^2+8x+10.
