" (iii) "x^(2)+(x)/(2)+1=0

x^(2)+(x)/(sqrt(2))+1=0

x^(2) + x/sqrt(2)+1=0

x^(2) + x/sqrt(2)+1=0

x^(2) + x/sqrt(2)+1=0

If the equations 2x^(2)+x+k=0 and x^(2)+(x)/(2)-1=0 have common roots. Then the value of k is

2x^(2) + x+1=0

2x^(2) + x+1=0

2x^(2) + x+1=0

2x^(2) + x+1=0

Verify rolle's theoram F(x)=x^(2)(1-x)^(2) in [0,1]
