Question 309643: I need help finding the real solution to this equation.
(1/2)x2 + x = 1
Answer by checkley77(12844) (Show Source): You can put this solution on YOUR website!
(1/2)x2 + x = 1
X^2/2+X-1=0
.5X^2+X-1=0

X=(-1+-[SQRT1^2-4*.5*-1])/2*.5
X=(-1+-SQRT[1+2)/1
X=-1+-SQRT3
X=-1+-1.732
X=1+1.732
X=.732 ANS.
X=-1-1.732
X=-2.732 ANS.
