x^{2} + x + 1 = 0

$x^{2} + x + 1 = 0$

Step 1

Once the quadratic is in standard form, the values of

a

$a$ ,

b

$b$ , and

c

$c$ can be found.

a x^{2} + b x + c

$a x^{2} + b x + c$

Step 2

Use the standard form of the equation to find

a

$a$ ,

b

$b$ , and

c

$c$ for this quadratic.

a = 1

$a = 1$ ,

b = 1

$b = 1$ ,

c = 1

$c = 1$
