Answer:
2(x + 3)(x + 1)(x - 4)
or 2x^3 - 26x - 24.
Step-by-step explanation:
We can write the polynomial if factor form:
P(x) = a(x + 3)(x + 1)(x - 4) where a is some constant.
Now, since f(-2) = 12 we can write :
12 = a(-2 + 3)(-2 + 1)(-2-4)
12 = 6a
a = 2.
So the polynomial is
2(x + 3)(x + 1)(x - 4).
Expanded that is
2(x + 3)(x^2 - 3x - 4)
= 2(x^3 - 3x^2 - 4x + 3x^2 - 9x - 12)
= 2x^3 - 26x - 24.
Answer:
what I got is a= 5/2
Step-by-step explanation:
remove the parentheses then you calculate then you move the terms then calculate the like terms and divide both sides.
I hope this helps
The angles get added.
Let <em>z</em> = <em>r</em> exp(<em>i</em> <em>θ</em>) and <em>w</em> = <em>s</em> exp(<em>i</em> <em>φ</em>). Then
<em>zw</em> = <em>rs</em> exp(<em>i</em> <em>θ</em>) exp(<em>i</em> <em>φ</em>) = <em>rs</em> exp(<em>i</em> (<em>θ</em> + <em>φ</em>))
Answer:
124
Step-by-step explanation:
You plug in the values for x in each respective equation.
a) f(3) = 3 + 1 which equals: 4.
so, f(3) = 4
b) g(3) = (3)^2 - 3 which equals 9 - 3, which equals 6.
so, g(3) = 6.
