TS EAMCET · Maths · Quadratic Equation
If and are the roots of the equation where are rational numbers, then the roots of the equation are
- A real and different
- B real and equal
- C purely imaginary
- D complex conjugate
Answer & Solution
Correct Answer
(B) real and equal
Step-by-step Solution
Detailed explanation
Given, 1+2 and 2-i are the roots of the equation x4+bx3+cx2+dx+e=0 where b,c,d,e are rational numbers, Now coefficient are rational so other two roots must be 1-2 & 2+i, Now we know the value of all four roots, using this we will find the value of…
