2.3, 2.6, 2 4/5
2 4/5= 2.8
Answer:
The answer is 18.
Step-by-step explanation:
You just need to plug in -7 to the equation 2x-4. You get -18, but absolute value is always positive, so its 18.
Answer:
Well rewriting literal equations can help you understand better and you'll have more room to write the answer and figure it out.
Step-by-step explanation:
Answer:
x^3 - 2x^2 + 9x - 18.
Step-by-step explanation:
The complex roots occur in conjugate pairs so there are 3 roots 2, 3i and -3i.
So we have:
P(x) = (x - 2)(x - 3i)(x + 3i)
= (x - 2)(x^2 - 9i^2)
= (x - 2)(x^2 - 9*-1)
= (x - 2)(x^2 + 9)
= x^3 + 9x - 2x^2 - 18
= x^3 - 2x^2 + 9x - 18.
I believe the answer is 2.5. I apologize if I'm wrong :/ =))
