Question
Question: If \(\frac{x^{2} + 34x - 71}{x^{2} + 2x - 7}\) then both the roots of the equation \(x\)....
If x2+2x−7x2+34x−71 then both the roots of the equation x.
A
Are real and negative
B
Have negative real parts
C
Are rational numbers
D
None of these
Answer
Have negative real parts
Explanation
Solution
The roots of the equations are given by
(−4,7)
(i) Let (4,−7)
Now if (−4,−7) ⇒ the roots are negative.
(ii) Let λx2+2x+3λ=0 then the roots are given by
λ=
Which are imaginary and have negative real part
−4
∴ In each case, the roots have negative real part.
