Question 200824
x^2 +x +sqrtx^2 +x -2 = 0
.
x^2 +x+x+x-2=0
.
x^2 +3x -2=0
.
use  Quadratic  Formula
.
a=1,,,,b= 3,,,,c=-2
.
x=[ -(3) +/- sqrt { (3)^2 -4 (1) (-2) } ] / 2(1)
.
x= [ -3 +/- sqrt { 9 +8 } ] /2
.
x= [-3 +/- 4.123 ] /2
.
x= .5615,,, -3.562
.
check  by  subst  into  original,  with  calc,,,,ok
