**Question 1.**

**Without solving, comment upon the nature of roots of each of the following equations:**

**(i) 7x² – 9x + 2 = 0**

**(ii) 6x² – 13x + 4 = 0**

**(iii) 25x² – 10x + 1 = 0**

**(iv) x² + 2√3 x – 9 = 0**

**(v) x² – ax – b² = 0**

**(vi) 2x² + 8x + 9 = 0**

**Solution:**

**Question 2.**

**Find the value of ‘p’, if the following quadratic equations have equal roots :**

**(i) 4x² – (p – 2) x + 1 = 0**

**(ii) x² + (p – 3) x + p = 0**

**Solution:**

**Question 3.**

**The equation 3x² – 12x + (n – 5) = 0 has equal roots. Find the value of n.**

**Solution:**

3x² – 12x + (n – 5) = 0

Here a = 3, b = -12, c = (n – 5)

D = b² – 4ac

**Question 4.**

**Find the value of ‘m’, if the following equation has equal roots :**

**(m – 2) x² – (5 + m) x + 16 = 0**

**Solution:**
