If the roots of x2 + 6x + 5 = 0 are α and β, then α + β = ……�

1.	If the roots of x2 + 6x + 5 = 0 are α and β, then α + β = ……………….. A) 5 B) -6 C) 6D) -1
Answer» Correct option is (B) -6 Given that roots of \(x^2+6x+5=0\) are \(\alpha\;and\;\beta.\) \(\therefore\) Sum of roots \(=\frac{\text{-coefficient of x}}{\text{coefficient of }x^2}=\frac{-6}1\) = -6 \(\Rightarrow\) \(\alpha+\beta\) = -6 Correct option is B) -6

If the roots of x2 + 6x + 5 = 0 are α and β, then α + β = ……………….. A) 5 B) -6 C) 6D) -1

Answer»

Correct option is (B) -6

Given that roots of \(x^2+6x+5=0\) are \(\alpha\;and\;\beta.\)

\(\therefore\) Sum of roots \(=\frac{\text{-coefficient of x}}{\text{coefficient of }x^2}=\frac{-6}1\) = -6

\(\Rightarrow\) \(\alpha+\beta\) = -6

Correct option is B) -6
