Question

If the discriminant of an equation is negative, which of the following is true of the equation

A it has two complex solutions
B it has one real solution
C it had two real solutions

Answer 1

A. It has two complex roots.

Explanation:

We are given that

Discriminant of an equation =negative

We have to find which is true about the equation .

Let quadratic equation

`ax^2+bx+c=0`

Discriminant=
`D=b^2-4ac`

If D < 0 , then the equation has complex roots.

Therefore, if the discriminant of an equation is negative then the equation has two complex roots.

Answer:A. It has two complex roots.

Answer 2

The answer is A. it has two complex solutions
