    Answer:

    x= 1

    x= -1

    Step-by-step explanation:

     - 4x^{2}  - 7 =  - 11 \\ subtract \: both \: sides \: by \: 7 \\  \\  - 4x^{2}  =  - 4 \\ divide \: both \: sides \: by \:  - 4 \\  \\ x^{2}  =  \frac{ - 4}{ - 4}  \\ divide \:  - 4 \: to \:  - 4 \\  \\ x ^{2}  = 1 \\ take \: square \: root \: of \: both \: sides \: of  \\  the \: equation \\  \\ x = 1 \\ x =  - 1
