UNIT II: Algebra - Quadratic Equations
Answers
k = 1, 3
Roots are ,
, Proved
Yes both are equal
2b = a + c, proved
q = 16
k = 16 for both the equation
k = 0, 1; x = -1/2
k = 4
p = -1, 3
k = 2
-56 so the equation is not real root
k = 2/3, -1
k = 4
To be proved
For equation I0 k = ± 16, ii) 16
k = 16
