Answer:

The roots are imaginary, there are no real roots.

Step-by-step explanation:

We've been given a quadratic equation, and we're asked to find the nature of the roots.

The equation is x² - 3x + 4√2​, where;

  • a = co-efficient of x² = 1
  • b = co-efficient of x = -3
  • c = constant term = 4√2 ‎

We know that the nature of the roots of a quadratic equation is given by its discriminant (D).‎‎

Discriminant (D) = b² - 4ac‎‎

1) If D > 0

  • Nature of roots: Roots are real, both the roots are distinct. (Unequal)‎‎

2) If D = 0

  • Nature of the roots: Roots are real, both the roots are equal.‎‎

3) If D < 0

  • Nature of the roots: Roots are imaginary, there are no real roots.‎

For the quadratic equation x² - 3x + 4√2​;

‎⇒ Discriminant (D) = b² - 4ac

⇒ Discriminant (D) = (-3)² - 4(1)(4√2)

⇒ Discriminant (D) = 9 - 16√2

⇒ Discriminant (D) = 9 - 16(1.414)

⇒ Discriminant (D) = 9 - 22.624

Discriminant (D) = -13.6274 (approx)

Here, D = -13.6274, meaning D < 0.

‎‎

The nature of the roots are imaginary, there are no real roots.
