Question

I can't factor thsi what i do? can u teach me?
with steps
x2+5x+7=O​

Answer 1

Answer:

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

Using the quadratic formula.

which is,

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

P(x)=x²+5x+7=0

a=1, b=5, c=7

by comparing with ax²+bx+c=0 (general form of a quadratic equation)

Here, as Discriminant, D<0,...thus, the roots are non real and are imaginary.

So, x∉R
