Solution :

  \:  \:  \:  \:  \:  \:  \: {4x}^{2}  - 25 = 0

 =  > (2x) ^{2}  -  {5}^{2}  = 0

 =  > (2x - 5)(2x + 5) = 0

 =  > 2x - 5 = 0 \:  \:  \:  \: or \:  \:  \:  \: 2x + 5 = 0

 =  > 2x = 5 \:  \:  \:  \: or \:  \:  \:  \: 2x =  - 5

 =  > x =  \frac{5}{2}  \:  \:  \:  \: or \:  \:  \:  \: x =  \frac{ - 5}{2} .
