# What is a long and complicated math equation that equals 15 [Solved] sqrt(([(3*4*5*6)-310]/2)) ((5!)/12) = 15 haha

(if u use a calculator put it in piece by piece or else u will get 9)

(Solution)
First complete the square
This is done by taking the x and y term (numbers in front of x and y not x^2 y^2) dividing it by 2 and squaring it and adding it to the other side so you get
x^2-10x 25 y^2-20y 100=0
now break it up
x^2-10x 25=0 and y^2-20y 100=0
trinomial factor it (draw an x put the last number on the top and the middle number on the bottom from each equation) now you want two numbers to put in the side of the x they will be the same number and must multiply to equal the top number and add to be the bottom number so for the x one i used used -5 (-5^2=25 and -5 -5=-10) and for the y i used -10 (-10^2=100 and -10 -10=-20) so those work now to write it in factored from its simply (x-5)^2 (y-10)^2=0 so now just take the opposite of the number in the ( ) for the answers so x=5 and y=10 because (5-5)^2 (10-10)^2=0 and to check you can plug it into the original equation to find that when x=5 and y=10 it will equal -125 as the original equations says so now x y=5 10 which equals 15 the number you wanted hope thats long enough and i explained my process well enough
