rodney models the factorization of a trinomial with algebra tiles as shown. rodney forgot to place x - tiles in zero pairs in the model of the trinomial. how many zero pairs of x - tiles should he place in the model? 1 2 3 4
Answer
Explanation:
Step1: Count positive x - tiles
There are 2 positive (x) - tiles.
Step2: Count negative x - tiles
There are 4 negative (x) - tiles.
Step3: Determine zero - pair number
To make zero - pairs ((+x) and (-x) together make a zero - pair), we take the minimum of the number of positive and negative (x) - tiles. The number of positive (x) - tiles is 2. So, we can make 2 zero - pairs.
Answer:
2
