Let x2=y. ⇒y2+1y+1=0. Now, D=b2−4ac. ⇒D=(1)2−4(1)(1)=1−4. ⇒D=−3. ⇒D<0. So, the given equation y2+y+1=0 has no real roots. ∴ the equation $$\left ( x^{2} + 1 \right )^{2} - x^{2} =0$ has no real roots. Hence, the correct answer is option [C].

WebNov 12, 2015 · 1 Answer Sorted by: 4 We have a x 2 + ( a + b) x + b = a x 2 + a x + b x + b = a x ( x + 1) + b ( x + 1) = ( x + 1) ( a x + b) Hence, x = − 1 and − b / a are the roots. Proceeding your way, we have a 2 + b 2 − 2 a b = ( a − b) 2, which is a non-negative discriminant.
