Question

Find the nature of roots for the quadratic equation 2 x - x + 1= 0

Answer 1

Answer:

discriminant

D= b²-4ac

D= -1²-4(2)(1)

D= 1-8

D= -7

since D<0

therefore roots are not real

Answer 2

Step-by-step explanation:

D = b^2-4ac

= (-1)^2 - 4× 2 × 1

= 1 - 8

= -7

D<0

henve the equation has no solution
