Question 233845

{{{red((m + 4))green((a-5)) + red((m + 4))green((a + 3)) }}}

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

{{{red((m + 4))(green((a-5)) + green((a + 3))) }}}

Remove the green parentheses inside the black parentheses:

{{{red((m + 4))(green(a-5) + green(a + 3)) }}}

Forget the colors, make everything black:

{{{(m + 4)(a-5 + a + 3) }}}

Combine like terms inside the second set of parentheses:

{{{(m+4)(2a-2)}}}

Factor 2 out of the second parentheses:

{{{(m+4)2(a-1)}}}

Put the 2 in front to make it look better:

{{{2(m+4)(a-1)}}}
