    The integers would be x and y.

    Therefore, we can suggest this system of equations:

    x+y=2

    xy=-24

    We can solve this system of equations by substitution method.

    x+y=2; ⇒y = (2-x)

    then:

    x (2-x) = - 24

    2x-x²=-24

    x²-2x-24=0

    x=[2⁺₋√ (4+96) ]/2 = (2⁺₋10) / 2

    we would have two possible solutions:

    x₁ = (2-10) / 2=-4 ⇒y₁ = (2-x) = 2+4=6

    x₂ = (2+10) / 2=6 ⇒y₂ = (2-x) = 2-6=-4

    We can see the numbers would be - 4 and 6.

    Answer: the numbers would be: - 4 and 6.
