Answer:
1. 2x²+x-1
Step-by-step explanation:
=(2x³+9x²+3x-4)÷(x+4)
=(x+1)(2x-1)(x+4)÷(x+4)
=2x²+x-1
CORRECT ME IF IM WRONG
Quotient of (8׳+27) ÷ (2×+3).
SOLUTION:
\frac{8 {x}^{3} + \: 27}{2x + 3}2x+38x3+27
Factor the numerator.
\frac{(2x \: + \: 3)(4 {x}^{2} - \: 6x \: + \: 9)}{2x + 3}2x+3(2x+3)(4x2−6x+9)
Cancel the common terms: (2x + 3)
= 4 {x}^{2} - 6x + 9=4x2−6x+9
ANSWER:
\red{\boxed{4x² - 6x + 9}}4x²−6x+9
