Angelina factored (x - 48) and wrote that it was equal to (x^2 - 4^2) ^2 (x^2 + 4^2). Use complete sentences to explain how you could confirm whether Angela's solution is correct. Prove your conclusion by multiplying out Angela's solution.

Harold Graves · Answer 1

(x^2 - 4^2) ^2 = x^4 - 4^4

(x^4 - 4^4) (x^2 + 4^2) = x^2 - 4^6

The Angela's solution is wrong cause when you multiply you get a different answer.
