Let be real numbers.
Suppose, are the roots of the equation and are the roots of the equation , where .
Statement .
Statement or .
Options
- AStatement 1 is true, Statement 2 is true, Statement 2 is a correct explanation for Statement 1.
- BStatement 1 is true, Statement 2 is true, Statement 2 is not a correct explanation for Statement 1.
- CStatement 1 is true, Statement 2 is false.
- DStatement 1 is false, Statement 2 is true
Correct answer
B. Statement 1 is true, Statement 2 is true, Statement 2 is not a correct explanation for Statement 1.
Step-by-step solution
Given, and are the roots of .
\alpha\frac{1}{\beta}a x^2+2 b x+c=0\alpha+\frac{1}{\beta}=\frac{-2 b}{a}\frac{\alpha}{\beta}=\frac{c}{a}
\text{ Now, }
Statement 1 is true.
Statement 2 is true.
Both Statement 1 and Statement 2 are true. But Statement 2 does not explain Statement 1.$
