Choose the correct simplification of (6x3 − 7x − 4) + (4x3 + 8x + 3). 2x3 − 15x − 7 10x3 + x − 1 2x3 + 15x + 6 10x3 − x − 1

The simplified form of given expression is  10x³ + x -1

Step-by-step explanation:

It is given an expression in variable x,

(6x³ − 7x − 4) + (4x³ + 8x + 3)

To find the simplified form

(6x³ − 7x − 4) + (4x³ + 8x + 3)

 = 6x³ + 4x³ - 7x + 8x - 4 + 3

 = 10x³ + x -1

Therefore the simplified form of given expression is  10x³ + x -1
