Answer 2

Heya user !!!

Here's the answer you are looking for

The condition for equal roots of the quadratic equation ax² + bx + c = 0 is that,

⏩ b² - 4ac = 0

⏩If b² - 4ac = 0, then

$x = \frac{ - b + \sqrt{ {b}^{2} - 4ac } }{2a} \: or \: x = \frac{ - b - \sqrt{ {b}^{2} - 4ac} }{2a} \\ x = \frac{ - b \: + 0}{2a} or \: x = \frac{ - b - 0}{2a} \\ x = \frac{ - b}{2a} \: or \: x = \frac{ - b}{2a} \\ \\ Both \: the \: roots \: are \: equal.$
