Answer

Explanation:

Step1: Recall standard - form of quadratic equation

The standard form of a quadratic equation is $ax^{2}+bx + c=0$.

Step2: Rewrite the given equation in standard form

Given $-6=x^{2}+4x - 1$. Move all terms to one side to get $x^{2}+4x-1 + 6=0$, which simplifies to $x^{2}+4x + 5=0$.

Answer:

c = 5
