The statement that is true of the equation is A . The equation has two real roots .
What is true of the equation ?
The discriminant of a quadratic equation is the part of the quadratic formula under the radical (b ² - 4ac ). In this case, the discriminant is :
( - 6 ) ² - 4 x 1 x 2 = 36 - 8
= 28
When the discriminant is positive , it has a real square root, and the quadratic formula reduces to two real solutions. Since 28 is a positive number, the equation has two real roots .
The options for the question are:
- The equation has two real roots.
- The equation has no real roots.
- The equation has one real root.
- The equation has complex roots.
