a. 2x^2+9x-5 = (2x-1)(x+5)
2x^2+9x-5 = (2x^2 +10x -x -5)
2x^2+9x-5 = (2x^2 +9x -5) --- CORRECT
b. 5x^2-13x-6 = (5x-3)(x+2)
5x^2-13x-6 = (5x^2 +10x -3x -6)
5x^2-13x-6 = (5x^2 +7x -6) --- NOT CORRECT
c. 32x-14x+15 = (3x=4)(x+3) --- ano yung sign sa (3x?4) tas feeling ko it's 3x^2, not 32x. (gawin kong 3x-4 yung 3x=4)
3x^2-14x+15 = (3x-4)(x+3)
3x^2-14x+15 = (3x^2 +9x -4x -12)
3x^2-14x+15 = (3x^2 +5x -12) --- NOT CORRECT
d. 3x^2-14x+15 = (3x-5)(x-3)
3x^2-14x+15 = (3x^2 -9x -5x +15)
3x^2-14x+15 = (3x^2 -14x +15) --- CORRECT
e. 14x^2-3x-5 = (7x-1)(2x+5)
14x^2-3x-5 = (14x^2 +35x -2x -5)
14x^2-3x-5 = (14x^2 +33x -5) --- NOT CORRECT kung -3x lang yung 2nd term but correct kung -33x yung 2nd term. but from what I see is -3x lang, so it is incorrect.
