Answer:
The term 6x should actually be 6x²
Step-by-step-explanation:
The illustration referenced, which depicts the multiplication of the trinomial with the binomial, is provided in the image below.
To identify where Chin's multiplication went wrong and to establish the correct expression, we'll analyze each multiplication performed. Therefore, we have:
3x*x² = 3x³
3x*2x = 6x² (the mistake occurred here, as Chin recorded it as 6x in the chart)
3x*4 = 12x
2*x²=2x²
2*2x = 4x
2*4 = 8
Thus, the term 6x should indeed be corrected to 6x²
The least common denominator needed to combine the variable terms is 15. The least common denominator for the constant terms is 21.
To properly complete the square, divide the b value by 2 and then square that result. For instance, if b equals 4, you would first halve it to get 2, and the square of 2 would give a result of 4.
We are required to tally the number of games scoring 15, 16, 17, and 18. There are 3 games with a score of 15, 2 games scoring 16, 5 games with a score of 17, and 3 games scoring 18. The total comes to 13 games.
