Solve x in each quadratic equation:


\begin{gathered} 2x^2-32=0 \\ 2x^2-32+32=0+32 \\ 2x^2=32 \\ (2x^2)/(2)=(32)/(2) \\ x^2=16 \\ √(x^2)=√(16) \\ x=\pm4 \end{gathered}

Solution set for equation 2x^2-32=0 is: (-4,4)

\begin{gathered} 4x^2-100=0 \\ 4x^2-100+100=0+100 \\ 4x^2=100 \\ (4x^2)/(4)=(100)/(4) \\ x^2=25 \\ √(x^2)=√(25) \\ x=\pm5 \end{gathered}

Solution set for equation 4x^2-100=0 is: (-5,5)

\begin{gathered} x^2-55=9 \\ x^2-55+55=9+55 \\ x^2=64 \\ √(x^2)=√(64) \\ x=\pm8 \end{gathered}
