Question

I can't factor thsi what i do? can u teach me?
with steps
X2+5x+7=O​

Answer 1

Answer:

its a quadratic equation with imaginary roots. It has no real roots as Discriminant is less than 0.

Here, p(x)=x²+5x+7=0

on comparing with ax²+bx+c=0

a=1, b=5, c=7

as,

$x = \frac{ - b ± \sqrt{ {b}^{2} - 4ac} }{2a}$

(QUADRATIC FORMULA)

$x = \frac{ - 5 + \sqrt{ - 3} }{2} \: or \: \frac{ - 5 - \sqrt{ - 3} }{2}$
