Let's make the first even integer m and the second even integer n. The square of the first, decreased by the second is 130 is:
-n=130 ---> Add n to each side
=130+n ---> Take the square root of each side
m=±
Let's look at the first square number above 130, which is
. <em>m</em> is 12, therefore the next consecutive even integer is 14.
=144
144-14=130
The two consecutive integers are 12 and 14
m=±
Let's look at the first square number above 130, which is
144-14=130
The two consecutive integers are 12 and 14
