Nature of roots of x−2x−1=x+42x+2 is
Two distinct real roots
Two equal real roots
No real roots
None of these
x−1x−1=x+42x+2 ,
⇒ x2 + x=0
⇒ D=b2−4ac
⇒b2−4ac > 0
⇒ 12−4×1×0>0
⇒ 1 > 0
Since, D > 0 roots are distinct and real
The nature of roots of x2−3x+2=0 will be:
Find the discriminant of the quadratic equation 3x2–5x+2=0 and find the nature of their roots.
