Answer: b = -6, 4
Step-by-step explanation:
Convert into factored form :
(b+6)(b-4)
Then make one of the terms 0.
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:
- 15
Step-by-step explanation:
29-11=18
18²+18²=p²
324+324=p²
p²=648
p=18√2
That's your answer.
