let first no. be = x
then , second = 20 - x ( given, sum is 20 )
A.T.Q.
x(20-x) = 36
20x - x^2 = 36
x^2-20x+36 = 0
x^2 - 18x - 2x +36 =0
x(x-18) -2(x-18)
(x-18)(x-2)
x = 18 and 2
then , second = 20 - x ( given, sum is 20 )
A.T.Q.
x(20-x) = 36
20x - x^2 = 36
x^2-20x+36 = 0
x^2 - 18x - 2x +36 =0
x(x-18) -2(x-18)
(x-18)(x-2)
x = 18 and 2
