Question

the root of the following quadratic equation is real and equal find k
m2-2m+1=0
​

Answer 1

Answer:

5 upon 6-3 upon 5(1 upon 3+2upon11)

Answer 2

Answer:

Step-by-step explanation:

Given quadratic equation is m² - 2m + 1 = 0

Comparing the given equation with ax²+ bx + c = 0 ,we have

a = 1 , b = - 2 and c = 1.

And it has equal root, then

Discriminant = D = b² - 4ac = ( - 2 )² - 4 ( 1 ) ( 1 ) = 4 - 4 = 0

Hence, the quadratic equation have real roots.
