Question

If the discriminant is 0, how many real solutions does the quadratic equation have?


2


1


3


0

Answer 1

I'd say 1 or 2 but I'm not sure

Answer 2

If Discriminant = 0 , then the equations will have 2 real and equal roots.

If Discriminant > 0 , then the equations will have 2 real roots

If Discriminant < 0 , then the equations will have 2 imaginary roots

Answer 3

So it's 2?? o.o

Answer 4

yes.. and both will be EQUAL

Answer 5

lol
that is like having one

Answer 6

if \(b^2-4ac=0\) then it is a perfect square
there is one zero
it is \(-\frac{b}{2a}\)

Answer 7

But the Theory of Quadratic Equations states that it has 2 Equal roots..

Answer 8

So it's not 2 i'm lost

Answer 9

it is one
not two
one

Answer 10

that one is often called a "repeated root" but it is one number

Answer 11

Alright, thank you.

Answer 12

for example if \((x-3)^2=0\) then \(x=3\) is the only solution

Answer 13

yw

Answer 14

The answer is 1 only.. but this is just an added information.. since the theory states there will be 2 roots... :)
