Consider statements in respect of ax²+bx+b=0 (a≠0):
- 1Product of roots equals sum of roots.
- 2Roots are always unequal and real. Which is/are correct?
Elementary MathematicsAlgebra
- A1 only
- B2 only
- CBoth 1 and 2
- DNeither 1 nor 2
Explanation
Sum=−b/a, product=b/a; equal iff b=0 or a=−1... not always. Discriminant b²−4ab not always >0. Answer D.
