Answer:
Option (C) Not Real and unequal.
Step-by-step explanation:
Given that,
- Quadratic polynomial ; 5x² - 4x + 5 = 0.
On comparing with ax² + bx + c = 0 , We get ;
❤ a = 5 , b = -4 , c = 5
We know,
Discriminant = b² - 4ac
[ Putting values ]
➡ (-4)² - 4 × 5 × 5
➡ 16 - 20 × 5
➡ 16 - 100
➡ -84
.°. Δ > 0
[ Discriminant is less than Zero ]
For information:
- Δ < 0 [ Discriminant is greater zero ]
Statement: Roots are real and unequal.
- Δ = 0 [ Discriminant is equal to zero]
Statement: Roots are real and equal.
