Question

the product of two successive number is 1980.find the smaller number

Answer 1

smaller number is 0 in sentences

Answer 2

Let the first number be a

Second number = a +1

According to question,

a (a +1) = 1980

=> a^2 + a = 1980

=> a^2 + a - 1980 = 0

=> a^2 + 45a - 44a - 1980 = 0

=> a (a +45) - 44(a +45) = 0

=> ( a - 44)(a + 45) = 0

a = 44 and - 45

Neglect negative value,

So, a = 44

First number = 44

Second number = 44 + 1 = 45
