find two number whose sym is 27 and product is 182
Answers
Let the first number be x and the second number is 27 - x. It is given that the product of these numbers is 182.
Let the first number be x and the second number is 27 - x.
Therefore, their product = x (27 - x)
It is given that the product of these numbers is 182.
Therefore, x(27 - x) = 182
⇒ x2 – 27x + 182 = 0
⇒ x2 – 13x - 14x + 182 = 0
⇒ x(x - 13) -14(x - 13) = 0
⇒ (x - 13)(x -14) = 0
Either x = -13 = 0 or x - 14 = 0
⇒ x = 13 or x = 14
If first number = 13, then
Other number = 27 - 13 = 14
If first number = 14, then
Other number = 27 - 14 = 13
Therefore, the numbers are 13 and 14.
Step-by-step explanation:
Let the 2 no.s be x and y.
Given that x+y = 27...(1)
Product = xy = 182...(2)
Substituting the value of x in (2) and putting in (1)
xy = 182
x = 182/y
x+y = 27
182/y+y = 27
182+y² = 27y
182-27y+y² = 0
By putting the formula of Quadratic Equation ,
y = 13
x+y = 27
x = 27-13 = 14
The no.s are 13 and 14..
