2. 

a = 5, b = 9, c = -4

This is because the equation should be equal to zero before finding the terms. 

The standard form is given by :

[tex] ax^{2} +bx +c=0 [/tex]

So we have to convert given equation in this form by bringing all terms to one side and making 0 on the other side.

[tex] 5x^{2} +9x=4 [/tex]

Now we have to bring 4 to the left side,

subtracting 4 on the left,

[tex] 5x^{2} +9x-4=0 [/tex]

Comparing our equation with standard form,

Answer : a=5, b=9 and c=-4 ( second option is right )
