After plugging in the a,b, and c values + discriminant of x^2 + 4x + 3

Question

what is the answer to the quadratic formula:

-b + √b^2 - 4ac

---------------------. = ?

2a

Answer 1

x^2 +4x + 3 = 0

(x+3)(x+1) = 0

x =-1, -3

x= -b/2a + or - (1/2a) sqr(b^2 -4ac) a=1, b=4, c=3

x= -4/2 + or - (1/2)sqr(16-12) = -2 + or - (1/2)sqr4 = -2 + or - 1 = -1, -3

x= -1, -3
