Step-by-step explanation: this answer is 100% correct for edge.nuity.

Answer 2

Step 2

Explanation:

Fiona did mistake step 2.

Use the distributive property to multiply -3 times each term in the trinomial.

The correct result is

-3(5x^2 - 2x + 7) = -15x^2 + 6x - 21

Fiona written -6x instead of + 6x.

That's the error.

The answer is "Step 2"

Hope you will understand the concept.

Thank you.
