Factor out the red factor and leave the sum of the green 
factors in black parentheses:

red%28%28m+%2B+4%29%29%28green%28%28a-5%29%29+%2B+green%28%28a+%2B+3%29%29%29+

Remove the green parentheses inside the black parentheses:

red%28%28m+%2B+4%29%29%28green%28a-5%29+%2B+green%28a+%2B+3%29%29+

Forget the colors, make everything black:

%28m+%2B+4%29%28a-5+%2B+a+%2B+3%29+

Combine like terms inside the second set of parentheses:

%28m%2B4%29%282a-2%29

Factor 2 out of the second parentheses:

%28m%2B4%292%28a-1%29

Put the 2 in front to make it look better:

2%28m%2B4%29%28a-1%29
