Question

Determine the nature of the roots for each of the following quadratic equations.
m-- 2m + 1 = 0​

Answer 1

Explanation:

m2 - 2m + 1 = 0 compare with ax2 + bx +

C = 0

We get,

» a = 1, b = = - 2, c = - 1

The value of discriminant is

:: b2 - 4ac

= -22 - 4(1)(1)

= 4-4

= 0

:: b2 - 4ac = 0. hence, roots are real and equall

Answer 2

Explanation:

first answer is correct
