Question

Describe the roots of the equation shown below.

3x^2+4x+2=0

A. There are two real, rational roots.
B. There are two real, irrational roots.
C. There is one real, double root.
D. There are two complex roots.

Answer 1

look at the discriminant (the square root part of quadratic formula)
\[D = b^{2} -4ac\]
if D > 0, 2 real roots
D < 0 , 2 complex roots
D = 0, 1 real double root

Answer 2

If D is perfect square, then roots are rational.....otherwise irrational

Answer 3

so the roots are rational

Answer 4
