Rewrite by completing the square. x^2 + 3x + 1.

x = 2.618, -0.382

Step-by-step explanation:

x²+3x+1=0

Using the formula [x+(b/2)]²-(b/2)+c , substitute all your variables.

[x+(3/2)²]-(3/2)²+1=0

[x+(3/2)²]-(9/4)+1=0

[x+(3/2)²]-(5/4)=0

x+(3/2)²=5/4

x-(3/2)=±√(5/4)

x=√(5/4)±(3/2)

x=√(5/4)+(3/2) , √(5/4)-(3/2)

x=2.618 , -0 382
