How do I simplify the following problem? 2x squared minus x minus 21 over 2 x squared minus 15x plus 28 Click to expand... Post these like this: (2x^2 - x - 21) / (2x^2 - 15x + 28) Factor each; 2x^2 - x - 21 = (2x - 7)(x + 3) Factor denominator, then simplify. If you can't, you need classroom help.
