Answer:

The formula for quadratic equation is
$\sqrt[n]{x+x^(2) } = 0$

Step-by-step explanation:

$ax^(2) + bx + c = 0\\a + b = -(b)/(a) \\ab = (c)/(a)\\\\a^(2) +b^(2) = (c)/(a)\\\\$

when c = 0,

((b)/(a))^(2) - 2 ((c)/(a))^(2) = - (b)/(a)

$(b)/(a) [( (b)/(a)) + 1] = 0\\b = 2c$

The formula for quadratic equation is

$x^(2) - (1 + 1)x + 1 = 0\\x^(2) - 2x + 1 = 0\\$

if roots are 1 then,

x^(2) - x = 0
