Q129 / 200 · AP EAMCET 2002 · Mathematics

To remove the second term of the equation $x^4-8 x^3+x^2-x+3=0$, diminish the roots of the equation by

  • A
    $1$
  • Correct answer
    B
    $2$
  • C
    $3$
  • D
    $4$

Solution

We have, $x^4-8 x^3+x^2-x+3=0$ $$ h=-\frac{\text { coefficient of } x^3}{\text { number of roots }}=\frac{-(-8)}{4}=2 $$

Hence, the correct answer is option: 'B'.
