Identify the values of a, b, and c that would be used in the quadraticformula to solve the equation - x2 + 5x = 7.a) a = -1, b = 5, c = 0b) a = 1, b = 5, c = 7c) a = -1, b = 5, c = -7d) a = 1, b = -5, c = 0

C) a= -1, b=5, c= -7

Step-by-step explanation:

To get the values of a, b and c we must first write the equation in the form

ax²+bx+c=0 where a b and c are the coefficients.

Therefore, -x² +5x=7 can also be written as:

-x²+5x-7=0

a= -1 ( coefficient of x²)

b=5 (coefficient of x)

c= -7 ( the constant in the equation)

a=-1, b=5 and c=-7

Step-by-step explanation:

We have the following equation:

→

Given the equation of a parabola: . By comparison, we know that:

a=-1, b=5 and c=-7

So the correct option is Option C.
