the roots of the qudratic equation    8x2  - 10 x + 3 = 0 are   and 2 where 2 > 1/2,then the  equation whose roots  are   100 and 100 is

x2 - x +1=0

x2+x+1=0

x2-x-1=0

x2 +x -1=0

### and at last as it is always..... rates are assured.....

p.s. the question is correct . i have checked it twice....

the equation :

3sin2x+2cos2x  + 31-sin2x+2sin2x =28 is satisfied for the values of x given by:

cos x=1

tanx = -1

tanx =1

none of these

### guys...... rates are assured......
