Question

x square + 3 x + 1 =0
what is x​

Answer 1

✖ = -2

PLEASE MARK I'M BRAINLIST

Answer 2

Answer: x2−3x+1=0

Considering the coefficients and constants in the equation

a=1 [Coefficient of x2]

b= -3 [Coefficient of x]

c = 1 [The constant term]

The formula for the discriminant of a quadratic equation is

D=b2−4ac

Substituting values for a, b and c

D=(−3)2−4∗1∗1

D=9−4

D=5

Now, the formula for finding 'x' using the discriminant is

x = (−b±√D)/2a

Substituting values for b, D and a in the above formula, you get

x = (3±√5)/2

Hence, the values for 'x' are

x = (3+√5)/2 and  (3−√5)/2
