Question

If the sum of two natural number is 45 and three protect is 324 find the numbere
​

Answer 1

You just need to find the equation for x-y.

Answer 2

Answer:

the numbers are 9 and 36

Step-by-step explanation:

I suppose the question as

If the sum of 2 natural no.s is 45 and their product is 324, find the numbers.

if so,

let the numbers be x and y

given x + y = 45 --------- (1)

  and x.y = 324 ---------- (2)

=> y = 324/x

substitute the value of y in (1)

=> x + (324/x) = 45

=> x² -45x +324 = 0

=> x²- 9x-36x+ (9)(36) = 0

=> x(x-9) - 36(x-9) = 0

=> (x-9)(x-36) = 0

=> x-9 = 0  (or) x-36=0

=> x=9 or x=36

substitute the value of x in (1),

=> 9+y = 45  (0r) 36+y = 45

=> y = 45-9 (or) y = 45-36

=> y=36 (or) y=9
