    EQUATION

    Solve the equation. Find all real solutions (Be sure to check for extraneous solutions.) \displaystyle x=1+ \sqrt{7-x}

    ANSWER:

    \quad\quad\quad\quad\quad\displaystyle x=1+ \sqrt{7-x}

    \quad\quad\quad\displaystyle x-1= \sqrt{7-x}

    \displaystyle  x²-2x+1=7-x

    \quad\displaystyle x²-x-6=0

    \displaystyle (x-3)(x+2)=0

    \quad\displaystyle\boxed {x=3}\quad\displaystyle \cancel{x=-2}
