{{{8a+12b = 4(2a+3b)}}}
-----------------------
{{{x^2+5x = x*x+5*x}}} Factor the x
{{{x^2+5x = x(x+5)}}}
-----------------------
{{{5xy+15x^2 = 5*x*y + 5*3*x*x}}} Factor 5x
{{{5xy+15x^2 = 5x(y+3x)}}}
-----------------------
{{{21x^3-14 = 7*3*x^3-7*2}}} Factor the 7
{{{7(3x^3-2)}}}
-----------------------
