Here are pairs of equivalent expressions in standard form and factored form. Find the missing symbols and numbers.

$x^{2} ◻ 16 x ◻ 17$ and $(x + 1) (x - 17)$

Compare your answer:

− and –. The completed expression is $x^{2} - 16 x - 17$ .

$x^{2} ◻ 16 x ◻ 17$ and $(x - 1) (x + 17)$

Compare your answer:

+ and –, respectively. The completed expression is $x^{2} + 16 x - 17$ .

$x^{2} + 3 x - 28$ and $(x + ◻) (x - ◻)$

Compare your answer:

7 and 4, respectively. The completed expression is $(x + 7) (x - 4)$ .

$x^{2} - 12 x - 28$ and $(x ◻ ◻) (x ◻ ◻)$

Compare your answer:

−14 and +2. The completed expression is $(x - 14) (x + 2)$ .
