Question

Solve the quadratic equation x square minus x + 1 by 2 is equal to zero

Answer 1

Answer:

x=√-3+1/2

Step-by-step explanation:

x^2-x+1/2=0

x^2-x+1=0

{x^2- 2 × x × 1/2+(1/2)^2} -(1/2)^2+1=0

(x-1/2)^2 -1/4+1=0

(x-1/2)^2 + -1+4/4=0

(x-1/2)^2 + 3/4=0

(x-1/2)^2=-3/4

(x-1/2)=√-3/√4

x=√-3/2 + 1/2=√-3+1 /2

=√-3+1/2
