Originally Posted by calculus0 where did the 2 come from? where it is -1/2(2) thank you the -1 is brought inside the brackets using then we have 0.5 multiplied by 2 seperate terms so they can be brought inside with 0.5 as common factor and now is a common factor so the -2 can be brought inside the brackets.
Thanks!!
