Answer:
D and F
Step-by-step explanation:
can be rewritten as
.
From there you can use the quadratic formula
(ignore the A, I can‘t seem to remove it), where a=1, b=4, and c=-8.
![x=\frac{-4±\sqrt{4^{2}-4(1)(-8)} }{2(1)}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-4%C2%B1%5Csqrt%7B4%5E%7B2%7D-4%281%29%28-8%29%7D%20%7D%7B2%281%29%7D)
Then you get ![x=\frac{-4±\sqrt{16+32}}{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-4%C2%B1%5Csqrt%7B16%2B32%7D%7D%7B2%7D)
Then you get ![x=\frac{-4±\sqrt{48} }{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-4%C2%B1%5Csqrt%7B48%7D%20%7D%7B2%7D)
So ![x=-2±\frac{4\sqrt{3} }{2}](https://tex.z-dn.net/?f=x%3D-2%C2%B1%5Cfrac%7B4%5Csqrt%7B3%7D%20%7D%7B2%7D)
Which means
or
which are choices D and F.
Answer:
C
Step-by-step explanation:
2|6+p|-3p³,
when p=-2
2|6+p|-3p³=2|6-2|-3(-2)³
=2(4)-3(-8)
=8+24
=32
Answer:
i believe it is x=4
Step-by-step explanation:
