Answer 1

Answer:

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

Step-by-step 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 : $(8x^4-7)+(3-2x^3 +9x^4) = 17x^4 -3x^3 -4$
