Answer:

  -2x +4

Step-by-step explanation:

We can write the polynomial p(x) in terms of the factors (x+2) and (x-3) as ...

  p(x) = (x+2)(x-3)q(x) +ax +b

Where ax+b is the remainder from division by x^2 -x -6 = (x+2)(x-3). The values of 'a' and 'b' can be found from ...

  p(-2) = 8 = -2a +b

  p(3) = -2 = 3a +b

Subtracting the first equation from the second gives ...

  (3a +b) -(-2a +b) = (-2) -(8)

  5a = -10

  a = -2

Then the first equation tells us ...

  8 = -2(-2) +b

  4 = b

So, the remainder from division by (x^2 -x -6) is (-2x +4).

The rectangle below has an area of 14x^4 + 6x^2 square meters. The width of the rectangle (in meters) is equal to the greatest c
elena-s [515]

Answer:

Width: 2x^{2}

Lenght: (7x^{2}+3)

Step-by-step explanation:

1. The prime factorization of the monomial is:

14x^{4}=2*7*x*x*x*x\\6x^{2}=2*3*x*x

2. The product of the common factors is:

2*x*x=2x^{2}

3. The greatest common monomial factor is: 2x^{2}

4.  The formula for calculate the area of a rectangle is:

A=L*W

Where L is the length and W is the width

5. Therefore, if the greatest common monomial factor monomial of the area of 14x^{4}+6x^{2} is  2x^{2} and the area is the product of the lenght and the width, you have that the lenght is:

2x^{2}(7x^{2}+3)

Length:

(7x^{2}+3)
