in this problem when he adds 2 to the other side he writes it as 2± √14 shouldent it be 2+± √14 or better yet ± √14+2 the first looks like 2 multiplied by ± √14

Take the example: 2 ± √25 since there are two solutions to the square root of [25], one being a positive number and the other being a negative number, as a result the value will either be 2 minus or plus the square root of [25].Simplifying: 1.) 2 ± (√25) 2.) 2 - (5) = -3 ; 2 + (5) = 7
