Answer: a=-7, b=+1, c=+4
Explanation:
The equation written in the standard form is written as
[tex]ax^2 + bx+c=0[/tex] (1)
where a and b are the coefficients of the second-order and first-order term, while c is the constant term.
The equation we have in this problem is
[tex]-7 x^2 +x-4=0[/tex] (2)
By comparing (1) with (2), we immediately see that:
a = -7
b = +1
c = +4
