It's useful to divide out the GCF first because it makes factoring easier as the coefficients are smaller requiring less steps.
Example where you don't factor GCF first...
4*-32 = -128
numerous factor pairs for 128 ... takes time to find the correct one
right factor pair is 16,-8
substitute for 8x
4x² + 16x - 8x - 32 = 0
group then factor
4x(x+4) - 8(x+4) = 0
group again
(4x-8)(x+4) = 0
Example of factoring GCF first
4x² + 8x - 32 = 0
4 is GCF
x² + 2x - 8 = 0
factor
(x+4)(x-2) = 0
Solving for x gives the same answer just less steps and simpler math when you factor GCF first.

Answer: A
Step-by-step explanation: its because if an atom gains a negative electrons it becomes a negative ion. if it were to loses a electron it would become a positive ion. the other answers are not able to do both
