1) Javier did not raise the coefficients to the third power

2) when Javier raised x to the third power, he wrote that (x^1)^3=x^4, but it equals x^3

3) In the last step, Javier divided the exponents. He should have used the quotient of powers property and subtracted them.

is there answer choices?
