Write the followi

Class 10th MHB - Mathematics Part-1 Quadratic Equations

Answer :

(1)

⇒

y² + 2y - 10 = 0;

a = 1, b = 2, c = -10

(2)

⇒

⇒ x² - 4x - 2 = 0;

a = 1, b = -4, c = -2

(3) ⇒

⇒

⇒ x² + 4x + 3 = 0;

a = 1, b = 4, c = 3

(4) ⇒

a = 1, b = 0, c = 9

(5) ⇒

;

a = 6, b = 3, c = 5

(6) ⇒

= 0

a = 1, b = 0, c = -22
