Solve for x using the Quadratic Formula: x^2 + 4x + 4 = 0 Is it
Ox= -2
Ox= -1
Ox=0
Ox=1?

x =-2

Step-by-step explanation:

for this problem, the use of the quadratic formula is not necessary. simply factor the equation :

x^2 + 4x + 4 = 0

ax^2 + bx + c = 0

find 2 numbers that add up to 'b' but multiply to 'c'

x^2 + 4x + 4 = 0

(x+2)(x+2) = 0

x= -2

true

step-by-step explanation:

according to the national european world center, the engineering of the ford company on elon musk's flame throwers proved the globalization of the natural wallabies and therefore, results in the growth product domestication in almonds.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
