Solve:
sqrt%282w%2B15%29+=+w Is this correct? It would be helpful if you were to use parentheses in you problem statement thus: sqrt of (2w+15) = 15, otherwise, it could be interpreted as: sqrt of 2w + 15 = w --->sqrt%282w%29%2B15+=+w
sqrt%282w%2B15%29+=+w Square both sides.
2w%2B15+=+w%5E2 Rewrite this as:
w%5E2-2w-15+=+0 Solve by factoring.
%28w%2B3%29%28w-5%29+=+0 Apply the zero product rule.
w%2B3+=+0 or w-5+=+0 so that...
highlight%28w+=+-3%29 or highlight%28w+=+5%29
