Solve by using the quadratic formula x^2+1=x

February 6th, 2011 @2:37 am

You start by moving x to the other side:

x^2 – x + 1 = 0

now:

A = coefficient in front of x^2 (which is 1)

B = coefficient in front of -x (which is -1)

C = 1

use these values in the quadratic formula

Okay Quadratic formula is fun we just learned in third grade today

kk

X^2-x+1=0

-b plus or minus Sqrt(b^2-4ac)

all over 2 a

so discriminant is -1^2 -4(1(1)

-3

1+- sqrt(-3)

over -2

(1+-isqrt(3))/-2

x^2 – x + 1 = 0

[1 +- sqrt(1-4)] / 2 = 1/2 +- sqrt(3) i/2
