what is the discriminant of x2 +6x +9=0

Sagot :

the formula for solving this equation is      ^         ( -b + or - (√b² - 4ac)2a
a = 1,      b=6,    c  = 9
the discriminant is the value under the sqrt sign
 thus the discriminant is      ^      6² - 4 .1 .9 = 0
the discriminant is        0

b^2-4ac
substitutes the following number according or from the given equation
a=1
b=6
c=9
(6)^2-4(1)(9)
36-36
the answer is 0

hope it will help you ^_^
