Factor the following expression. 10x^5 + 5x^3 - 14x^2 - 7 a. (5x^3 + 7) (2x^2 -1) b. (5x^4 + 7) (2x -1) c. (5x^4 - 7) (2x + 1) d. (5x^3 - 7) (2x^2 + 1) so, i took the test already a million times already and i keep failing because of questions similar to this. i'd appreciate if you also explained the process instead of just giving an answer. you! ps: (5x^4 - 7) (2x + 1) is not the answer.
