the correct question is
The product of two consecutive even integers is 120. Find the integers

let
x-----------> first even integer
x+2-------> second consecutive even integer

we know that
x*(x+2)=120-------> x
²+2x-120=0

using a graph tool----> to resolve the second order equation
see the attached figure

the solution is
x=10

therefore
first even integer is 10
second consecutive even integer is (10+2)----> 12

the answer is
10 and 12
