Umm.. and the question is
Answer:
we have 2 real solutions
Step-by-step explanation:
ax^2 + bx+c
discriminant
b^2-4ac
6x=-2x^2-3
subtract 6x from each side
0 = -2x^2 -6x-3
a= -2
b=-6
c=-3
b^2-4ac = (-6)^2 - 4(-2) (-3)
36 - 24
12
if > 0 2 real solutions
= 0 1 real solution
< 0 2 complex solution
since 12 > 0 we have 2 real solutions
