Masteriza [31]

Answer:

Final answer is c=-7.

Step-by-step explanation:

Given equation is $0=-x^2+4x-7$ .

Now question says that Misha wrote the quadratic equation 0=-x2+4x-7 in standard form. Now we need to find about what is the value of c in her equation.

We know that standard form of quadratic equation is given by $ax^2+bx+c=0$ .

compare given equation with the standard form, we find that -7 is written in place of +c

so that means +c=-7

or c=-7

Hence final answer is c=-7.
