उत्तर
The given equation is
3x2 - 6x + 5 = 0
Here, a = 3, b = -6 and c = 5
Discriminant
= b2 - 4ac
= (-6)2 - 4 x 3 x 5
= 36 - 60
= -24 < 0
imaginary roots.

Complete the following activity to determine the nature of the roots of the quadratic equation x2 + 2x – 9 = 0 :
Solution :
Compare x2 + 2x – 9 = 0 with ax2 + bx + c = 0
a = 1, b = 2, c = `square`
∴ b2 – 4ac = (2)2 – 4 × `square` × `square`
Δ = 4 + `square` = 40
∴ b2 – 4ac > 0
∴ The roots of the equation are real and unequal.
