![\bf \stackrel{\textit{product of 2 and the }\sqrt{\qquad }\textit{ of other terms}}{2(\sqrt{(s+1)x^2})(\sqrt{1})}~~=~~\stackrel{\textit{middle term of the trinomial}}{(s-2)x} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ 2\sqrt{(s+1)x^2}=(s-2)x\implies 2x\sqrt{s+1}=(s-2)x\implies 2\sqrt{s+1}=s-2](/tpl/images/0379/9189/924fd.png)
