If discriminant (b^2 -4ac>0) how many real solutions
MaRussiya [10]

Answer:

If Discriminant,b^{2} -4ac >0

Then it has Two Real Solutions.

Step-by-step explanation:

To Find:

If discriminant (b^2 -4ac>0) how many real solutions

Solution:

Consider a Quadratic Equation in General Form as

ax^{2} +bx+c=0

then,

b^{2} -4ac is called as Discriminant.

So,

If Discriminant,b^{2} -4ac >0

Then it has Two Real Solutions.

If Discriminant,b^{2} -4ac < 0

Then it has Two Imaginary Solutions.

If Discriminant,b^{2} -4ac=0

Then it has Two Equal and Real Solutions.
