Step-by-step explanation:
Given that :-
(4x³-5x²-8x+7)+(2x-3x²+9x³-4)-(3x+2x³-9x²)
To find:-
Simplify (4x³-5x²-8x+7)+(2x-3x²+9x³-4)-(3x+2x³-9x²)
Solution:-
(4x³-5x²-8x+7)+(2x-3x²+9x³-4)-(3x+2x³-9x²)
=>4x³-5x²-8x+7+2x-3x²+9x³-4-3x-2x³+9x²
=>(4x³+9x³-2x³)+(-5x²-3x²+9x²)+(-8x+2x-3x)+(7-4)
=>(13x³-2x³)+(9x²-8x²)+(2x-11x)+(3)
Therefore, 11x³+x²-9x+3
Answer:-
(4x³-5x²-8x+7)+(2x-3x²+9x³-4)-(3x+2x³-9x²) = 11x³+x²-9x+3
