Answer 1

`(8x^4-7)+(3-2x^3 +9x^4) =17x^4 -3x^3 -4`

Explanation:

Here, the given expression is:
`(8x^4-7)+(3-2x^3+9x^4)`

Simplifying the given expression, we get:

`(8x^4-7)+(3-2x^3 +9x^4) = (8x^4+9x^4 -3x^3 -7 +3)\\= 17x^4-3x^3 - 4\\\implies (8x^4-7)+(3-2x^3 +9x^4) = 17x^4-3x^3 - 4`

Hence, on simplification :
`(8x^4-7)+(3-2x^3 +9x^4) = 17x^4 -3x^3 -4`
