Question

If x,y,z belongs to whole numbers and x+y=5;x+z=y;xyz=12 then find x+y+z????​

Answer 1

Answer:

WKT ,X,y and z belongs to whole number

First write each term in terms of X

x+y=5

x=5-y EQ 1

x+z =y

x+z=5-x. EQ 2

xyz=12

x(5-x)(5-2x)=12

( -x^2 + 5x )(5-2x)=12

( -5x^2+25 x )-(-2x^3 -10x^2)=12

2x^3 + 5x^2 +25x-12=0

solve this,. when u get value of X equate it in EQ 1 n 2 u will get y n z value

ALL THE BEST
