    Answer:

    The solutions for the equation x^2\:-\:27=\:67 are x=\sqrt{94},\:x=-\sqrt{94}.

    Step-by-step explanation:

    To find the solutions for the equation x^2\:-\:27=\:67 you must:

    \mathrm{Add\:}27\mathrm{\:to\:both\:sides}\\\\x^2-27+27=67+27

    \mathrm{Simplify}\\\\x^2=94

    \mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}\\\\x=\sqrt{94},\:x=-\sqrt{94}
