Write a polynomial, P(x), in factored form given the following requirements.
Tju [1.3M]

Answer:

P(x) = - 5(x + 2)²(x - 3)

Step-by-step explanation:

Given roots x = - 2 with multiplicity 2 and x = 3 , then the factors are

(x + 2)² and (x - 3)

P(x) is then the product of the factors, that is

P(x) = a(x + 2)²(x - 3) ← a is a multiplier

To find a substitute (2, 80) into P(x)

80 = a(2 + 2)²(2 - 3) = a(16)(- 1) = - 16a ( divide both sides by - 16 )

a = - 5

P(x) = - 5(x + 2)²(x - 3)

What is the focus of the parabola? y=−1/4x2−x+3
alex41 [277]

Answer:  Focus = (-2, 3)

<u>Step-by-step explanation:</u>

y=-\dfrac{1}{4}x^2-x+3\\\\\rightarrow a=-\dfrac{1}{4},\ b=-1

First let's find the vertex. We do that by finding the Axis-Of-Symmetry:

AOS: x=\dfrac{-b}{2a}\quad =\dfrac{-(-1)}{2(\frac{-1}{4})}=\dfrac{1}{-\frac{1}{2}}=-2

Then finding the maximum by inputting x = -2 into the given equation:

y=-\dfrac{1}{4}(-2)^2-(-2)+3\\\\y=-1+2+3\\\\y=4

The vertex is: (-2, 4)

Now let's find p, which is the distance from the vertex to the focus:

a=\dfrac{1}{4p}\\\\\\-\dfrac{1}{4}=\dfrac{1}{4p}\\\\\\p=-1

The vertex is (-2, 4) and p = -1

The focus is (-2, 4 + p) = (-2, 4 - 1) = (-2, 3)

A symbol used to represent an unknown value or quantity
bixtya [17]

Variables represent unknowns.  They are often letters (like x) but can also be other symbols like Greek numerics.

Hope this helps!!
