Question

Greatest common factor of -4x to the 4 power minus -8x to the 3 power?

Answer 1

This question is ambiguous because we don’t know if the two numbers are -4x^4 and -8x^3 or (-4x)^4 and (-8x)^3. In the first case 4x^3 is present in both and nothing else is. In the second case (4x)^3 is the largest common factor.
