Question

The zeros of the polynomial x^2+2x + 3 are 1 point a) real b) not real c) irrational d) rational

Answer 1

Step-by-step explanation:

Given quadratic is 2x 2+3x+2=0

Comparing it with standard from of quadratic equation ax 2 +bx+c=0, we get a=2,b=3,c=2

Thus discriminant of the given quadratic is

D=b

2 −4ac=9−16=−7<0

Hence roots of given quadratic are imaginary.

Thus choice D is correct
