Answer 1

Step-by-step explanation:

-12x2-25x-12=0 

Two solutions were found :

 x = -4/3 = -1.333

 x = -3/4 = -0.750

Step by step solution :

Step  1  :

Equation at the end of step  1  :

((0 - (22•3x2)) - 25x) - 12 = 0

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   -12x2 - 25x - 12  =   -1 • (12x2 + 25x + 12)
