★ANSWER★

Let the one number be x and the other number be ( x + 2 ) .

Product of these numbers = 168

\begin{gathered}\sf\Longrightarrow x(x+2) = 168 \\\\\Longrightarrow x^2+2x = 168 \\\\\Longrightarrow x^2+2x+1^2= 168 + 1^2 \ \ \ \ \ \ ( Square \ completion \ method )\\\\\Longrightarrow (x+1)^2 = 169 \\\\\Longrightarrow x+1 = \pm 13 \\\\If \ x+1 = +13 \ ,\bf { \ x = 12} \\\\\sf If \ x+1 = -13 \ , \bf \ x = -14\end{gathered}

⟹x(x+2)=168

⟹x

+2x=168

⟹x

+2x+1

=168+1

(Square completion method)

⟹(x+1)

2

=169

⟹x+1=±13

If x+1=+13 , x=12

If x+1=−13 , x=−14

The numbers are 12 and 14 or -12 and -14 .

Answer 2

Answer:

12,14

Explanation:

let's take number as x, x+2

so x(x+2)=168

x^2+2x-168=0

solve it to get x= 12

so numbers are 12,14
