Is  $\left(x+4\right)\left(x+2\right)$  equivalent to  $x^2+6x+8$  ?

• Yes

• No

Is  $\left(x-10\right)\left(x-3\right)$  equivalent to  $x^2-13x-30$  ?

• Yes

• No

Select ALL expressions that are equivalent to:

 $x-5$  

•  $x+\left(-5\right)$  

•  $x-\left(-5\right)$  

•  $-5+x$  

•  $-5-x$  

•  $5-x$  

Here is a pair of equivalent expressions--one in standard form and the other in factored form. Find the missing number. (enter numbers only)

 $x^2+12x+32\ =\ \left(x+4\right)\left(x\ +\ ?\ \ \right)$  

Here is a pair of equivalent expressions--one in standard form and the other in factored form. Find the missing number.

 $x^2-12x+35\ =\ \left(x-5\right)\left(x\ +\ ?\ \ \right)$  

Here is a pair of equivalent expressions--one in standard form and the other in factored form. Find the missing number.

 $x^2-9x+20\ =\ \left(x-4\right)\left(x\ +\ ?\ \ \right)$
