Question

If the equation:-
$\sf \purple{mx² + 2x + m = 0 }$
is satisfied by only one real value of x, then the values of m are ______ and _____?
$\sf \red {Find \: the \: two \: values \: of \: x. }$
​

Answer 1

Answer:

Mx² + 2x + m = 0

Here,

A = m , B = 2 and C = m

Discriminant ( D ) = 0

B² - 4ac = 0

(2)² - 4m² = 0

4m² = 4

m² = 1

m= +_1
