REASON :
Given equation -
![(-3)/(4){x}^(2)+2=0](https://img.qammunity.org/2020/formulas/mathematics/high-school/bh870aaa12ffmizncz740cfknfqnznstaw.png)
when, written in general form equation is
(on multiplying both sides by -1)
Now this is quadratic equation in general form, where
[coefficient of x^2]
b= 0 [coefficient of x]
c= -2 [constant term]
Hence, c= -2
