Evaluate :
1 ) `x^2 + 3 = 0`
2 ) `-x^2 + x -2 =0`
3 )` sqrt(2)x^2 + x + sqrt(2) = 0 `
4 ) `x^2 + x + 1 /sqrt(2)`

sqrt(5) x^2 - sqrt(3)x + sqrt(2) = 0 , find x

(4) sqrt(3)x^(2)+2x-sqrt(3)=0

2sqrt(3)x^(2)+x-5sqrt(3)=0

x^(2)-(sqrt(2)+1)x+sqrt(2)=0

x^2 - (sqrt 3 + 1) x + sqrt 3 = 0

(1) x^(2)-(sqrt(2)+1)x+sqrt(2)=0

(x-sqrt(2))^(2)-sqrt(2)(x+1)=0

x^(2)+(x)/(sqrt(2))+1=0

The equation of a circle of radius 1 touching the circles x^2 + y^2 - 2 |x| = 0 is: (A) x^2 + y^2 + 2sqrt(3x) - 2 = 0 (B) x^2 + y^2 - 2sqrt(3)y+2=0 (C) x^2 + y^2 + 2sqrt(3) y + 2 = 0 (D) x^2 + y^2 + 2 sqrt(3) x + 2 = 0

(x+sqrt(2))(x-sqrt(3))=0
