Mischa wrote the quadratic equation 0 = –x2 + 4x – 7 in standard form. what is the value of c in her equation

Mischa wrote the quadratic equation 0 = –x2 + 4x – 7 in standard form

The standard form of quadratic equation is

When y=0 then the standard equation becomes

Now we compare the given equation  with and find the value of a, b,c

-x^2 can be written as -1x^2

a= -1 , b=4  and c=-7

The value of c is -7

where is the figure

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
