The product of two numbers is 36 and their sum is 37. What is their difference
Answers
Answer:
AnsWer :
x = 36 , 1.
y = 1 , 36.
SolutioN :
Let,
the number be x and y.
Case 1.
product of two numbers is 36
→ x * y = 36.
Case 2.
their sum is 37.
→ x + y = 37.
Now, Taking Equation ( 1 )
→ x * y = 36.
→ y = 36 / x _____ ( 3 )
Now, Putting the value of x = 36 / y in Equation ( 2 )
→ x + y = 37.
→ x + 36/ x = 37.
→ x² + 36 = 37x.
→ x² - 37x + 36 = 0.
Compare With General Equation.
ax² + bx + c = 0.
Where as,
a = 1.
b = - 37.
c = 36.
→ x² - 36x - x + 36 = 0.
→ x ( x - 36 ) - 1 ( x - 36 ) = 0.
→ ( x - 1 )( x - 36 ) = 0.
Either,
→ x - 1 = 0.
→ x = 1.
Or,
→ x - 36 = 0.
→ x = 36.
Now , putting the value of x = 36 and 1 in Equation ( 3 )
→ y = 36 / x.
→ y = 36 / 36.
→ y = 1.
Or,
→ y = 36 / 1.
→ y = 36.
Therefore, the value of number is x = 36 , 1 and y = 1 , 36.
Answer : 1,36
Step-by-step explanation:
let the both numbers be x and y respectively -
ATQ-
XY = 36. (1)
X +Y = 37 (2)
X = 37 -Y (3) by equation (2)
putting value of x in equation 1
37-y (y) = 36
-y² + 37y - 36 = 0
- ( y² -37y + 36 )= 0
y²- 36y - y + 36 = 0
y ( y - 36) -1 (y - 36 ) = 0
( y-1 ) (y -36) = 0
so, y = 1 or 36
if y =1 then X = 36
if y=36 then X = 1
