Answer:

The two consecutive positive integers are 4 and 6.

Step-by-step explanation:

Let x be an even integer, then the next even integer is (x+2).


The sum of the squares of these even integers is 52.


We can write the following equation and solve for x.


x^2+(x+2)^2=52.

We expand to get,

x^2+x^2+4x+4=52.

We simplify to get,

2x^2+4x+4-52=0.


This gives us,

2x^2+4x-48=0


We divide through by 2 to get,

x^2+2x-24=0.

This is now a quadratic trinomial

We split the middle term to get,


x^2+6x-4x-24=0.


We factor to obtain,

x(x+6)-4(x+6)=0


\Rightarrow (x+6)(x-4)=0


\Rightarrow (x+6)=0 or (x-4)=0


\Rightarrow x=-6 or x=4


We discard x=-6 since it is not a positive integer.

\therefore x=4


Hence the two consecutive positive even integers are,

4

and

4+2=6

Answer:

4 and 6


Step-by-step explanation:

one number = x

other number = x + 2


x² + (x + 2)² = 52

x² + x² + 4x + 4 = 52

2x² + 4x - 48 = 0

x² + 2x - 24 = 0

(x - 4)(x + 6) = 0

x = 4 or x = -6


Since x is positive

x = 4

x + 2 = 6
