If x+y=25 and x*y=135, What are x and y？
y = 25 - x....so.....
x(25 - x) = 135 simplify
25x - x^2 = 135 rearrange
x^2 - 25x + 135 = 0
The two solutions are :
[25 + sqrt(85)] / 2 and [ 25 - sqrt(85)] 2 whichever x is, y is the other.....!!!
Good to see you, TM........!!!!!!
Good to be back :D
Hi Takahiro,
