Answer:
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
