Question

If the sum of the roots of the equation

(a + 1) x² + (2a + 3)x + (3a + 4) = 0 is –1, then the product of the roots is –

• A. 0
• B. 1
• C. 2
• D. 3

Answer 1

Answer: (C)

2

Answer 2

$\frac{- (2a + 3)}{a + 1}$ = – 1 Ž a = – 2

\ Product = $\frac{3a + 4}{a + 1}$ = $\frac{3( - 2) + 4}{- 2 + 1}$ = 2
