Chin made an error in his chart showing the multiplication of the binomial by the trinomial. Which change can be made to correct

stealth61 [152]

Answer:

The expression 6x should be 6x^2.

Step-by-step explanation:

Given is the chart of multiplication of the binomial by the trinomial.

Let's check each element in the chart:-

3x times x^2 = 3x^3

3x times 2x = 6x^2

3x times 4 = 12x

2 times x^2 = 2x^2

2 times 2x = 4x

2 times 4 = 8

From the given chart, we can identify that 6x should be 6x^2.

Hence. option B is correct, i.e. The expression 6x should be 6x^2.
