  • It is a typo error. It should read: "2(2x)(3)=12x. So instead of a + sign it should be close-open parentheses. It has to be corrected in the original and upload it again. Thanks for pointing it out. The answer is correct, but we got sloppy in the symbols. It will get done within the next 2 weeks. Again, thanks.
