x= 1st integer

x+1= 2nd integer

x(x+1) = 72

x^ + 1x + 72

x^ + 1x -72 = 0

(x+9)(x-8)

if u solve u'll get x=-9 and x=8

x can't be negative.

so x=8

x=8=1st integer

x+1=8+1=9=2nd integer.

x+1= 2nd integer

x(x+1) = 72

x^ + 1x + 72

x^ + 1x -72 = 0

(x+9)(x-8)

if u solve u'll get x=-9 and x=8

x can't be negative.

so x=8

x=8=1st integer

x+1=8+1=9=2nd integer.

**Let the First Number be x so second Number be x + 1**

According to given Condition

x(x + 1) = 72

x² + x = 72

x² + x - 72 = 0

x² - 8x + 9x - 72 = 0

x(x - 8) +9(x - 9) = 0

(x + 9)(x - 8) = 0

**x = 8 ,x cant be negative nine because it is a whole number**

**First No = 7**

**Second No. = x + 1 = 8 + 1 = 9**
