Hiii mate....
Step-by-step explanation:
Let the first number be X and the second number will be 27 - x
Also given that the product of these numbers = 182
First no.X second no. = 182
X ( 27 - X ) = 182
27X - X2 = 182
0 = X2 - 27X + 182
X2 - 27 X + 182 = 0
we factorise by splitting the middle term method.....
X2 - 13X - 14X + 182 = 0
X ( X -13 ) - 14 ( X - 13 ) = 0
( X - 14 ) ( X - 13 ) = 0
X - 14 = 0 , X - 13 = 0
X = 14 , X = 13
Hence 13 and the 14 are the roots of the equation ....
For X = 13
first number x = 13
second number = 27 - X = 27 - 13
= 14
for x = 14
first number x = 14
second number = 27 - X = 27 - 14
= 13
Hence the two numbers are 13 and the 14 .....
