Answer:
The value of c is [tex]5[/tex]
Step-by-step explanation:
we know that
The standard form of the quadratic equation is equal to
[tex]ax^{2} +bx+c=0[/tex]
In this problem we have
[tex]-6=x^{2}+4x-1[/tex]
Convert to standard form
Equate the quadratic equation to zero
[tex]x^{2}+4x-1+6=0[/tex]
[tex]x^{2}+4x+5=0[/tex]
so
[tex]a=1\\b=4\\c=5[/tex]
