Question

when solving x^2+4x=-9 what interger or fraction needs to be added to both sides to complete the square

Answer 1

What is 1/2 the coefficient of the x term?

Answer 2

Using the base y=ax^2+bx+c,
In a perfect square trinomial, (b/2)^2 is c

Answer 3

I have done (-6)^2-6(1)(-1)/2(1) but after that I am stuck

Answer 4

x^2+4x=-9
x^2+4x + 4 = -5
(x+2)^2 = -5
I'm not sure what you want to find, so I stop here.
