c = -7 is the right answer
Step-by-step explanation:
The standard for of quadratic equation is:
[tex]ax^2+bx+c = 0[/tex]
We have to compare any quadrati equation with standard form to get the value of a,b and c
Given equation is:
[tex]0= -x^2+4x-7[/tex]
This can also be written as:
[tex]-x^2+4x-7=0[/tex]
Comparing with the standard form we get
a = -1
b = 4
c = -7
So,
c = -7 is the right answer
