Alessandro wrote the quadratic equation -6=x2+4x-1 in standard form. What is the value of c in his new equation? c=-6
c=-1
c=5
c=7

Given:

A quadratic equation is

To find:

The standard form of the given equation and find the value of c.

Solution:

The standard form of a quadratic equation is

              ...(i)

We have,

It can be rewritten as

           ...(ii)

On comparing (i) and (ii), we get

Therefore, the value of c is equal to 5 and the correct option is C.
