Question

find roots of the quadratic equation : 2x^2 + 2x + 1 =0
I think I'm getting wrong answer.

Answer 1

Step-by-step explanation:

Discriminant of this equation i.e

$\sqrt{ {b}^{2} - 4ac } = \sqrt{ - 4}$

( a- coefficient of x2. b- coefficient of x. c -constant term)

is lesser than zero so it has imaginary root or in simple language no real number can satisfy this equation so you are not getting any answer

understand!!!! because every square is positive but this square is coming negative so its square root has no real value

HOPE THIS CLEARS YOUR DOUBT SO PLEASE MARK ME BRAINLIEST

Answer 2

Answer:

No real solution

Step-by-step explanation:

since according to quadratic formula D=b^2-4ac

must be greater or equal to 0 but here

D= 2^2-8

=4-8=-4 so therefore it has no real solution.
