Answer:
Discriminant is 17 and it has 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 1 real root
• [tx]b^2-4ac<0[/tex] yields no real roots
where a=4, b=-7, and c=2
.
It has 2 real roots
