Answer:
 yields 2 real roots
 yields 2 real roots
Step-by-step explanation:
To find the number of real roots for a quadratic, we apply the discriminate. The discriminate is the inside portion of the square root from the quadratic formula.
•	 yields 2 real roots
 yields 2 real roots
•	 yields 1 real root
 yields 1 real root
•	[tx]b^2-4ac<0[/tex] yields no real roots
Example: 
 where a=4, b=-7, and c=2
 where a=4, b=-7, and c=2
 .
.
It has 2 real roots
