If we set the equation equal to 0, we can factor it to find its roots:
x² + 4x + 4 = 0
(x + 2)(x + 2) = 0
x = -2
This graph has one root, a double root, at -2. This means that a single point, which must be the vertex of the parabola, touches the x-axis at (-2, 0)
Answer:
84m³ (A) should be correct
I am not sure what the answer is but covert them into a decimal and then divide it
A: x= 6+3 squareroot 10 ... Its letter A
