    Factoring 2x² + 5x - 12 when the x² coefficient isn't 1

    My Teacher taught me a method called slide and divide. 2x^2 +5x -12, you multiply the coefficient of 2x^2 times -12. X^2 +5x-24, from there you factor normally...Once you get the factors, you divide the number of by the coefficient you used before. One little trick that you must...
