Question

When B2-4ac=0, the roots are? ​

Answer 1

Answer:

equal

Step-by-step explanation:

hope it helps you.

Answer 2

As we know,

• Nature of the roots depends on the value of b² – 4ac.

• b² – 4ac is called discriminant of quadratic equation ax² + bx + c = 0

The conditions:

• If b² – 4ac > 0 ⇒ the roots are real and unequal.

• If b² – 4ac = 0 ⇒ the roots are real and equal.

• If b² – 4ac < 0 ⇒ the roots are imaginary.

• If b² – 4ac is a perfect square ⇒ the roots are rational and unequal.

• If b² – 4ac is positive and not a perfect square ⇒ the roots are irrational and unequal.

$\boxed{\bold{\sf{Answer:If \ b^2-4ac = 0 \implies the \ roots \ are \ real \ and \ equal.}}}$
