Question

The sum of the roots of the quadratic equation X² + 1 = 0 is equal to ---------

Answer 1

Answer:

$0$

Step-by-step explanation:

$for \: roots \: \alpha \: and \: \beta$

$\alpha + \beta = \frac{ - b}{a}$

$thereore \: for \: {x}^{2} + 0x+1 = 0$

$\frac{ - b}{a} = \frac{ - (0)}{1} = 0$

you can also verify this by actually factorizing. the roots will come as 1 and -1. so, on adding them you get 0 (duh).
