Answer 1

Answer:

c=-504 and b= 3

x²+(a-b)x-c =0

Answer 2

Answer:

18)

let two roots are a & b ,

A/q,

a = 1/b

ab= 1

product of roots = c/a

c/a = c/2 = 1

C = 2 (Ans.)

19)

let one number be X

other number = (x-3)

A/q,

x(x-3) = 504

x² - 3x - 504 = 0

x² - 24x + 21x - 5o4 = 0

x(x-24) + 21(x - 24) = 0

(x-24)(x+21) = 0

x = 24 , other number = 21 (Ans.)
