Fiona wrote out the description of each step for her multiplication of the binomial and trinomial (2x – 3)(5x2 – 2x + 7). A table titled Fiona's Product with 2 columns and five rows. The first column is labeled steps with 4 steps shown. The second column is labeled result and shows 5 result expressions. In which step did Fiona make an error? Step 1 Step 2 Step 3 Step 4

The descriptions of each step are given the multiplications of the bionomical and the trinomial i.e (2x – 3)(5x2 – 2x + 7). The titled Fiona's product has the 2 columns and the 5 rows. The first Colum is labeled as with 4 steps The second Colum is labeled as a result and the fifth is expression.

Using the distributive property and multiplying by -3 times each term of the trinomial. Thus, -3(5x^2 - 2x + 7) = -15x^2 + 6x - 21 Fiona written -6x instead of + 6x. This is the error. Hence the answer is "Step 2"
