Answer:

Final answer is (3x-y)(x+y).

Step-by-step explanation:

Given expression is 3x^2+2xy-y^2.

Now we need to factor the given expression 3x^2+2xy-y^2 completely. Let's use factor by grouping method.

3x^2+2xy-y^2

=3x^2+3xy-xy-y^2

=3x(x+y)-y(x+y)

=(3x-y)(x+y)

Hence final answer is (3x-y)(x+y).

(3x−y)(x+y) is the answer but did you mean to put 3x^2 + 2xy - y^2 as your answer?

Find the generating function for the sequence 1,-2,4,-8, 16, ...
kirill [66]

Answer:

  a(x)=\dfrac{1}{1+2x}

Step-by-step explanation:

The generating function a(x) produces a power series ...

  a(x)=a_0+a_1x+a_2x^2+a_3x^3+\dots

where the coefficients are the elements of the given sequence.

We observe that the given sequence has the recurrence relation ...

  a_0=1;a_n=-2a_{n-1} \quad\text{for n $>$ 0}

This can be rearranged to ...

  a_n+2a_{n-1}=0

We can formulate this in terms of a(x) as follows, then solve for a(x).

\sum\limits^{\infty}_{n=1} {a_{n}x^n} =a(x)-a_0 \quad\text{and}\\\\\sum\limits^{\infty}_{n=1} {2a_{n-1}x^n} =(2x)a(x) \quad\text{so}\\\\\sum\limits^{\infty}_{n=1} {(a_n+2a_{n-1})x^n}=0=a(x)-a_0+2xa(x)\\\\a(x)=\dfrac{a_0}{1+2x}=\dfrac{1}{1+2x}

The generating function is ...

  a(x) = 1/(1+2x)

Give the equation of the circle centered at the origin and passing through the point (0,-8)
Norma-Jean [14]

Answer:

The answer to your question is x ² + y² = 64

Step-by-step explanation:

Process

1.- Find the length of the radius

C (0, 0)

P (0, -8)

d = \sqrt{(x2 - x1)^{2}+ (y2 - y1)^{2}  }

d = \sqrt{(0- 0)^{2}+ (-8 - 0)^{2}  }

d = \sqrt{64}

d = 8

2.- Find the equation of the circle

    (x - h)^{2} + (y - k)^{2} = r^{2} \\

h = 0   and k = 0

    (x - 0)^{2} + (y - 0)^{2} = 8^{2}

            x² + y² = 64
