Step 2
Step-by-step 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.
