Sagot :
(4+√10)(4-√10)
=16-4√10+4√10-10
=6
------------------------------
(4+√10)+(4-√10)
=4+√10+4-√10
=8
----------------------------
The numbers are:
4+√10, and 4-√10
=16-4√10+4√10-10
=6
------------------------------
(4+√10)+(4-√10)
=4+√10+4-√10
=8
----------------------------
The numbers are:
4+√10, and 4-√10
this can be found by using substitution.
let number one be x and two be y.
xy = 6
x + y = 8
x=8-y subs this into "xy=6"
y(8-y)=6
expand and you will have a quad eqn and then just find y and use that to find x
