Step-by-step explanation:

Let x be the first number and x + 6 be the second

So we have...

[tex] {(x + 6)}^{2} - {x}^{2} = 144[/tex]

Expand and rearrange:

[tex] {x}^{2} + 12x + 36 - {x}^{2} - 144 = 0[/tex]

Simplify:

[tex]12x + 36 = 144[/tex]

Subtract 36 from each side:

[tex]12x =108[/tex]

Divide both sides by 12:

[tex]x = 9[/tex]

9 is the First Number

And so we can conclude that:

[tex]x + 6 = 15[/tex]

15 is the Second Number

Hope this helps!!
