24 The quadratic equation 8 sec2θ - 6 secθ +1 =0 has Infinitely many roots Exactly two roots Exactly four roots No roots
25 If a > 0,b > 0, c > 0 then the roots of the equation ax2+ bx + c =0 are Real and negative Non-real with negative real parts Real and positive Nothing can be said
26 if one root of the equation ix2 - 2(i + 1) x +(2 - i)= 0 is 2 - i then the other root is -i 2 + i i 2 - i
27 If the roots of ax2 + b =0 are real and distinct then ab > 0 a = 0 ab < 0 a > 0,b > 0
28 If ax + bx + c =0 is satisfied by every value of x,then b = 0,c = 0 c = 0 b = 0 a = b = c = 0
29 Both the roots of the equation (x -b) (x - c ) + (x -c) (x-a) +(x-a) (x-b) = 0 are always Positive Negative Real None of these
