Question

3. Error Analysis Mercedes states that when

multiplying 4x³(x³ + 2x² − 3) the product
is 4x9 + 8x6 - 12x³. What was Mercedes's
error?

Answer 1

Answer: Mercedes didn't follow the exponent multiplication rule.

Step-by-step explanation: When you are multiplying exponents, you add them. Therefore, the correct term from the multiplication would be :
`4x^6+8x^5-12x^3`. Mercedes actually multiplied the exponents instead of adding and therefore it was wrong.
