Answers
Answer:
Now, according to division algorithm
Dividend = Divisor × Quotient + Reminder
2x^4+3x^3-2x^2-9x-12 = x^2-3 × 2x^2+3x+4 + 0
solve it......

Answer:
The answer will be (2x² + 3x +4)
Step-by-step explanation:
- Factorize the polynomial:
The given polynomial is = 2x⁴+3x³-2x²-9x-12
= (2x⁴ - 2x² - 12) + (3x³ - 9x)
= 2(x⁴ - x² - 6) + 3x(x² - 3)
= 2{x⁴ - (3-2)x² - 6} + 3x(x² - 3)
= 2(x⁴ - 3x² + 2x² - 6) + 3x(x² - 3)
= 2{x²( x²-3) + 2(x² - 3)} + 3x(x² - 3)
= 2( x²-3)(x²+2) + 3x(x² - 3)
= (x² - 3){2(x²+2) + 3x}
= (x² - 3)(2x² + 3x +4)
- Dividing it by x²-3 we get, (x² - 3)(2x² + 3x +4)/(x²-3)
= (2x² + 3x +4)
