Question

lf b2 - 4ac= 0, then the roots of ax2 + bx + c = 0 are​

Answer 1

Answer:

If b² - 4ac = 0, then the roots of ax² + bx + c = 0 are real and equal.

Additional information :-

For an equation ax² + bx + c = 0, b² - 4ac is called the discriminant and helps in determining the nature of the roots of a quadratic equation.

→ If b² - 4ac = 0, then the roots of ax² + bx + c = 0 are real and equal.

→ If b² - 4ac > 0, then the roots of ax² + bx + c = 0 are real and unequal.

[ ie, if the value of b² - 4ac is a positive integer, then the root are real and unequal. ]

→ If b² - 4ac < 0, then the roots of ax² + bx + c = 0 are not real.

[ ie, if the value of b² - 4ac is a negative Integer, then the roots do not exist. ]

Hope this helps you :)
