The general form of quadratic equation which is solved by using the quadratic formula is

a x² + b x + c = 0  

Where: a, b and c are constants


by comparing the previous formula  with the given options 
The most appropriate equations are

0.25x² +0.8x − 8 =0

3x² − 4x = 15


so, the correct answer is options 2 and 3
