First :+x%2Ax=x%5E2
Outer :+x%28-2%29=-2x
Inner :+%286%29x=6x
Last : 6%28-2%29=-12
Add them all together and simplify
+%28x%2B6%29%28x-2%29=x%5E2-2x%2B6x-12=highlight%28x%5E2%2B4x-12%29%0D%0A

First :+3x%2A%28-x%29=-3x%5E2
Outer :+3x%284%29=12x
Inner :+%28-2%29%28-x%29=2x
Last : %28-2%294=-8
Add them all together and simplify
+%283x-2%29%28-x%2B4%29=-3x%5E2%2B12x%2B2x-8=highlight%28-3x%5E2%2B14x-8%29%0D%0A
