### Two numbers that when added equal 70 and when multiplied equal 1225?

35 and 35.
The solution is first let X and Y be the two unknown numbers.
Then X + Y = 70 and X multiplied by Y equals 1225.
Simplifying the first equation and substituted to the second
equation it will become
X to the power of two subtracted by 70X and added by 1225, and then
simplifying by quadratic equation then it will come up of an answer
of 35..
